Sorting, refreshing, almost every action using the title bar actions kick me back to Frontpage.
Even if Lemmy servers has issues, pressing Refresh will brings back the Frontpage. Pressing back then closes the app.
My suspicion is that maybe error handling changed, and when error occures the app just resets? I don't know, but before the update it didn't reset everything on communication error. Lemmy.world tends to throw lots of errors.
These are some serious, breaking issues IMO.
Hope it will be fixed soon!
(would be nice to either disable back button exiting or give the user a toast that pressing back again will quit. if you ask me, back button on frontpage could open up the left drawer without exiting - like Sync did)
