I can’t seem to find any setting to enable automatic updates in Discover. Currently, I get a ping for available updates, nearly every day, and I then have to manually click “Update”. I would much prefer for Flatpaks to automatically update themselves in the same way that Gnome Software does it.

I understand the negative sentiment that many have towards automatic updates, but, for Flatpaks, it’s a risk that I am completely willing to take.

Update #1:

There appears to be a setting for toggling automatic updates in System Settings>Software Update>Update software>Automatically; however, it appears to be a known bug that this is currently broken with flatpak.
