Push Notifications Delayed or Missing

[Dubstar_04]

Push notifications for telegram / gmail can be delayed or not appear at all.

For example a telegram message arrived at 15.01pm and the notification arrived at 16.32pm.

Currently using an MX4 with OTA7.

Are there any logs that will help?

Are you seeing bug #1515344?

[Dubstar_04 (dubstar-04)]

Hi Pat,

If I am honest, the behaviour I am seeing is so unpredictable I'm not sure how it behaves.

Sometimes notifications appear, sometimes they don't. Some appear when I unlock the device, some play a notification sound when the device is locked.

This bug report is more aimed at the fact that some notifications don't arrive at all and some arrive late, hours after the message has been read on the device.

I know its not much use but I'm not sure what I can provide to be more useful.

Using arale on rc-proposed, same issue:

Message in telegram.
Telegram app closed.
No notification.
I open telegram, open a group to see new incoming message.
I close telegram.
I randomly receive those messages (already read) notification.
Some message have then delayed notification, some message no notification at all.

Please ask me log files if needed

[cm-t 🦄🏂🌈🎵 (cm-t)]

I just rebooted my device.

Two messag was reveived and read in a telegram grouo.
I open group to anwser (talking about this bug)
I send my message... I focus app scope
Screen is not locked and tadaa, i get a notification, and a minute later, without screen locked, the 2nd notification (both about those two message received and read before the rebooot)

I beleive this is not about bug #1515344

[Michał Karnicki (karni)]

Telegram app is not smart enough (though current source could enable adding this behavior) to figure it should not show notifications for messages that have been already read. This is usually fine if notifications arrive properly (usually only by accident you could open Telegram, read a just-received message [for which you didn't see a notification], and close Telegram *before* the push notification arrives). But it's not fine when push messages are delayed, in which case it's possible to notice this behavior.

"I randomly receive those messages (already read) notification.
Some message have then delayed notification, some message no notification at all."

You "randomly" receive 'already read' message notifications depending on when they've been sent and if you've read them *and* backgrounded or killed the Telegram app. Notification may arrive delayed (for which the problem can be anywhere between Telegram itself, through our push infrastructure, to push daemon on the device), but it would be good to understand if, in fact, some message notifications don't arrive at all, or you just happen to foreground Telegram when you expect those notifications. You may know this, but for clarification I'll state that notifications will not show when Telegram is in foreground* (which means if some arrive, and you foreground Telegram, the following ones won't show).

* with the exception of bug #1515344 -- I thought originally I filed the bug, but essentially the problem was then the phone is locked *AND* the app (for which notifications you expect) is in foreground. In this specific case, they would not show/blip/arrive. If the phone was locked, but the app was not in foreground, I think it worked fine. Anyway, just providing as much details as I can.

[Michał Karnicki (karni)]

oh, this is the original one that I thought of when describing possibilities here: bug 1507510

[cm-t 🦄🏂🌈🎵 (cm-t)]

This bug has been reproduced on arale r189 and r190

[Michał Karnicki (karni)]

What's the rough delay magnitude you're experiencing? (Or you mean notifications not arriving at all, even after significant time?)

[Dubstar_04 (dubstar-04)]

@karni for me its quite unpredictable. Some notifications don't arrive some are an hour late. Could it be a problem with the server?

[Dubstar_04 (dubstar-04)]

I first noticed this problem when I was using sils caxton. I was sending myself push notifications for email from my home server and I noticed that some notifications didn't arrive and sometimes a number of them arrived at once spanning several hours of notifications. Thats what makes me think its a server issue. Just speculating...

[Michał Karnicki (karni)]

That's an important detail. Delayed notifications from Telegram *and* Caxton rule out Telegram server's blame and seems to point to an issue on our push infra side.

[Dubstar_04 (dubstar-04)]

Its it possible for users to view their push data server side?

[Michał Karnicki (karni)]

No, only one team within Canonical (or even less than that) would have access to push server instances.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Pat McGowan (pat-mcgowan)]

What sort of data connection do you have when this occurs?
Is Wifi enabled, cellular data?
Have you recently moved out of range of a wifi connection?

[Dubstar_04 (dubstar-04)]

I think it has happened on both. The caxton notifications issues were while on wifi as I was testing at home when it happened. The recent telegram notification issues been while on mobile data.

[Dubstar_04 (dubstar-04)]

Push client log: http://paste.ubuntu.com/13900227/

Attached a screenshot to show messages for which no notifications were received.

I'm on wifi at home.

[Jonas G. Drange (jonas-drange)]

Ubuntu push checks for status every five minutes. Does this correspond with
the delay you are experiencing?

If so, the fix is for you to decide the status check interval yourself via
System Settings, not a fix in Ubuntu push.

The delay of the original bug report was 1.5 hours but some notifications just don't arrive as shown in #17.

[Dubstar_04 (dubstar-04)]

I just (18:31pm) recieved a telegram notification for a message that came at 16.18pm.

Push log: http://paste.ubuntu.com/13901599/

Screen shot of message attached.

[Dubstar_04 (dubstar-04)]

Also note that the notifications are not in the order that the messages were sent.

[Dubstar_04 (dubstar-04)]

Here is another one.

Message recieved at 16.26pm
Notification recieved at 18.39pm

Push Log: http://paste.ubuntu.com/13901780/

[Dubstar_04 (dubstar-04)]

And another.

Message received at 16.33pm

Is this still on the stable channel with OTA8?

[Dubstar_04 (dubstar-04)]

Yes OTA8.

[Michał Karnicki (karni)]

Comment by Timo:

Ok I had received a notification at 4:21 in the night of a message that had been sent at 22:03 that I had already read. The Bq (OTA8) was blinking on the desk without me touching it.

[SB (emehntehtt)]

After some trouble with notifications on Telegram on the phone I did a factory reset, but that didnt change anything, I receive no notifications whatsoever on my phone, no led and no sound notifications on Telegram. Sms notifications work fine. I received one notification though with a delay of like 10 hours. BQ Aquaris E4.5 with OTA-8.

[Esperanto (pablo-foche)]

I have the same problem here. Yesterday I had a huge delay receiving telegram notifications, today I don't receive notifications at all. BQ Aquaris E4.5 and OTA-8.

[Esperanto (pablo-foche)]

I was wrong. Notifications arrive also today but with a delay of eight hours.

[Jean-Baptiste Lallement (jibel)]

Problem still exists on rc-proposed arale r191. I received today a notification at 22:17 for a message sent at 14:11 (8 hours delay)

[Jonas G. Drange (jonas-drange)]

I can confirm the behaviour, but only for Telegram. The Hello World app is not affected by this on my phone. I cannot reproduce this behaviour for Telegram on iOS—even though it's the same account.

So this does not point to ubuntu-push off the bat. We'll have to investigate this further on Monday.

[SB (emehntehtt)]

I received two notifications since my last message, but they were duplicates of notifications received earlier this day. I am guessing something is broken in Ubuntu push servers that relay messages, but I am just speculating as people I chatted with report no problems with Telegram on Android, everything works fine for them. SMS and Gmail notifications seem to work fine.

But I hope this can be fixed soon as having broken Telegram is a big issue for people that use Ubuntu phones as their daily drivers.

[Esperanto (pablo-foche)]

Everything back to normal a couple of hours ago. Whatever you did it works. I'm receiving telegram notifications in time again.

[SB (emehntehtt)]

I just tested it and I also received a proper notification, seems it is fixed at the moment, hopefully permanently. It would be good if someone writes more on what caused these issues with Telegram notifications.

[cm-t 🦄🏂🌈🎵 (cm-t)]

Just to let you know, a friend as a 'standard user' (no dev option enabled or manualy .click installed) has the same issue on E4.5 on stable channel

[Michał Karnicki (karni)]

Although we started investigating, we have not yet changed anything (for the users who reported that "it's back to normal).

[Michał Karnicki (karni)]

We have made some preliminary investigation on our end and at this point I have reached out to Telegram server guys. I will update the bug if I get any significant news.

[Michał Karnicki (karni)]

Supposedly there have been some issues on Telegram end, and they have been addressed this last Sunday. I'm getting notifications now reliaby for Telegram, but some users (e.g. mzanetti) still reports ~5 min delays. I have requested further feedback on Telegram and inquired whether we should keep digging, or it's still something on their end. I have also heard users have reported slowness on other platforms (I haven't experienced it, so can't confirm that bit).

[SB (emehntehtt)]

This evening I am experiencing lack of notifications again, few came in with a big delay, Android user on the other side has no issues.

[Michał Karnicki (karni)]

Sorry for late reply, had extended hols and catching up.

Notifications seem to be working fine for me. As mentioned, I believe Telegram addressed some problems on their end, but I have no further insight into potential problems that persist. Are you still having issues with notifications as of today? Thanks.

[SB (emehntehtt)]

They are working fine since then, had a few "silent" messages yesterday where the message arrived with no sound and no notification in the taskbar, yet were seen in Telegram, today they work normally, probably something on Telegram's end.

[Michał Karnicki (karni)]

Okay. I am marking this bug as invalid. We shall re-open if this affects users heavily, at which point I will reach out to Telegram staff again.

[Xoyan (gg-0103)]

My telegram still have the same problem ... im not getting notifications on time sometime also missing ... i uninstall and reinstall again .. but still same . its really annoying. please help.

[Michał Karnicki (karni)]

Reached out to Telegram. They thanked and said they found a problem, it was a new one. Should be fixed now.

[Jonas G. Drange (jonas-drange)]

Seems to have solved it for me. @gg-0103 any change for you?

[Jonas G. Drange (jonas-drange)]

Please note that there are three ways for notifications to be disabled:
1. In System Settings -> Notifications -> Telegram
2. Telegram -> Settings -> Notifications
3. Telegram -> User -> (Click user icon) -> Notifications

[jEzEk (jezek)]

I'm experiencing a huge delay for notifications. Counted in hours (like half of day). Today also I restarted my phone (7:00 am) and on launch a notification froze my lock screen. The notification was from allteady readed message (10:00 pm, from day before). It was not the first time notifications were late (like half of a day). BQ Aquaris 5HD

[jEzEk (jezek)]

After my previous post #47, notifications began miracuosly working. But a day ago and today, there is delay again. I opened telegram app (20:50) and there are unread messages (delivered 6:25 and 14:55), but i didn't got any notifications for them. This bug is not fixed.

[SB (emehntehtt)]

I dont have this issue so I am guessing that it is a temporary problem with Telegram servers like before.

[Earendil02 (earendil002)]

I consistently experience 9-10 minutes delay, BQ E4.5 OTA-12.
Tis is extremely annoying and is dragging for several months, a fix is overdue.

[John Lenton (chipaca)]

has anybody checked manually sending a push notification (either using the user+device token for telegram itself (it used to print it somewhere), or using "shove")? Historically the delays were on telegram's end.

[David Kaplan (davidkiryat8)]

Using OTA-13 on a Nexus4 dual boot with bq-aquarius.en rc channel, I constantly get delays in Telegram app input receptions and notifications. This morning for example I was on cellular data (non WIFI) mode and a message was sent to me at 9:04 but arrived at 9:58.
Does any one have a work around or can I supply any log that may be helpful?

[Andrew (amdrew)]

I am using Aquaris E4.5 Ubuntu Edition
For about 1 week I have been receiving notifications 2 hours after the actual message arrived

[Andrew (amdrew)]

Also, even once message is read the Telegram icon in the shortcut bar (which slides from the left of the screen) keeps an indicator which shows an unread message. Even though it's been read.

[Leon083 (leon083)]

I'm using aquaris E 5.
It's some days that notification arrive 1 hour late, even after i already read the message..
