Comment 14 for bug 1318834

"Applications can no longer access your [gmail address]. Choose Online Accounts from the user menu to reinstate access to this account."

This bug is still present in 17.04 with Gnome. I don't think it was an issue until I entered the information for my Google account in Online Accounts. Now, the error pops up at every login and is quite annoying.

I have tried to remove it, add it again, remove it and remove authorization via Google as well as adding it and turning off all applications. Nothing works.
