@aaribaud You could add the Fedilab repo to your F-Droid to get the updates directly from there. You can find the repo link in the FAQ section of the Fedilab web site.
In recent versions of F-Droid after adding the repo you have to make sure to also have it set as the "preferred" one for the given app.
Also, make sure to export your settings, you'll probably have to do the uninstall/reinstall dance when you switch over since the two repos sign with different keys.
@apps I uninstalled fedilab from within F-Droid, I uninstalled F-Droid, I installed fedilab from Google play and opened it. I still was logged in, in fedilab from Google play. (This feels kind of strange).
So I deleted the complete storage data from the Google Play App, uninstalled fedilab, shut off my phone, restarted it, installed fedilab again.
RESULTS: - I'm still logged in inside of fedilab. - I'm still not getting push notifications.
@apps Sorry to still bother you, but i logged out of my instance in the connection screen, then logged in again in the connection screen (after selecting my instance).
@apps Thanks for your support. It resets every time, when leaving the screen (I know you preiously said it's just an interface flaw - but maybe not?). I got 3.29.2 from Google play installed
