flatpak software is not shown in gnome-software

[fossfreedom]

I installed gnome-software-plugin-flatpak which install flatpak and a few other packaged.

After a reboot I opened gnome-software and at the top of the app under the headerbar I saw "Sorry, something went wrong" popup.

I couldnt find any flatpaks shown in the software center.

Is there something else we need to-do to get flatpaks working in 17.10?

Subsequently I can confirm that I can install flatpaks via the command line though using the flathub command line webpage.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

The gnome-software-plugin-flatpak was known to have issues in 3.26, would you be able to try again with Ubuntu 18.04 + gnome-software 3.28 ?

It's not showing any updates for me in 19.10, and hasn't for quite some time.
