There are some issues in the FDroid build, that have been identified and are working on fixing and will be releasing a hot fix soon. In the meanwhile, we are working on delisting the latest build on F-Droid so more people dont get impacted.
Not sure why @setalp ‘s reply was flagged, as I was going to mark it as the solution.
The GitHub apk works, and Ente have removed the faulty update from F-Droid and rolled it back to the previous working version, hopefully they will fix it soon. I suggest everyone moves on to the GitHub apk if you haven’t already.
