Check that your instance is correct (lemmy.world) and try again when the server works better. Right now the server seems to be having a lot of trouble loading pages, etc, and maybe that’s why it’s not working for you.

I’m using liftoff:https://play.google.com/store/apps/details?id=com.liftoffapp.liftoff&pli=1

Apk of liftoff if the google play won’t let you install the app: https://github.com/liftoff-app/liftoff/releases/tag/v0.10.1

others: https://lemmy.world/post/465785 and https://lemmy.world/post/401441

I hope more communities move to lemmy, especially the mental health/support ones.

As for lemmy in general, I have to say that apart from the lack of videos, it’s not bad at all, even the android apps are already better than the official reddit one (terribly slow for some reason).
