It's great. Probably the most reliable app for me. I had some trouble when I had an account on another instance. That's probably your problem. Lemmy world should stabilize soon.
I've tried jerboa, thunder, wefwef, connect and liftoff. I was having some problems, but they may have been more related to the instance I was on.
In the last couple days, I've been mostly gravitating to wefwef and liftoff. I'd say wefwef is my favorite, but how it handles the back gesture on android is annoying.
I had an issue yesterday where I couldn't post a comment without going into the web interface to pick a language.
