The app on android was fine for a while, but the past few days it keeps logging me out and then my account is no longer saved. If I enter my account info it appear to have me logged in for a refresh or two, but then I can't get to my profile and then I show up as Anonymous again.
I don't think it's entirely the app. I've had it happen to my Lemmy.world account using Jerboa and Connect, so I think this must be them working on stuff after the hack.
It's on the instance, it happened to me too some hours ago and all of a sudden all clients stopped working (complaining about me not being logged in). One of the workarounds for the hack was actually invalidating all sessions, so maybe we were all logged off.

I think this is related to the recent security vulnerability that affected, notably, lemmy.world. Even unaffected instances mostly decided to invalidate existing user sessions just to be sure and this required resetting Jerboa and some other apps that presumably hold onto a cached version of your auth token even if you remove the account and re-add it or something. So it was necessary to clear the app cache and storage to reset it and add accounts again.
I had that last night but it seems fine this morning. I made accounts at mastodon and lemm.ee so I could still get info on when things were back up and running on .world
