If you use apps, you can't even relogin. Expect this if you're using app like boost, sync etc. However you are okay if you're using Voyager because it is browser-based.
I've been having these issues at lemmy.sdf.org when they update to 0.19, for about two weeks now I think. I use Sync and the dev are aware of the issue. But there's still no fix even though the dev is very quick in fixing bugs before. So I think, this is a major issue for app and it will take quite a while before we will see any fix.
To talk about needing to migrate off or the platform dying because they are on a release not even a month old is a bit hysterical.
To say it is a bit hysterical is an understatement.
Cant you just cross-compile instead? I am pretty sure their is at least some ways to compile arm docker images on amd machine.
