Mine was also f-droid, but my wife’s wasn’t. Experienced issue on both :(

I don’t have the time, or quite frankly the inclination, to try, when I can just switch to immich and/or syncthing (currently evaluating my options right now). I will say we noticed photos missing from my wife’s upload as well, so that’s two android clients and one server. That plus the complaints in the link I provided are all the evidence I need to bail.

This is in Ontario
