Pages not loading or error'ing out, general usability stuff, like pictures in the feed snapping back to small/icon size causing the feed to jump around, posts opening in the same window and going back takes me all the way to the top/start of my feed, the confusion around interoperability between instances (can I just log in with my account on another instance? Do i need a new account?), etc.

I'm on mobile, so maybe that's a large part of my complaint, but when ya come from Reddit, it's hard to not see things Reddit does well that you miss.

It's also very likely some of this is simply user error, I am not an expert, but I feel like if it's confusing or not intuitive for me, then it's probably room for improvement.

Edit: Idk what changes were made in the most recent update to Lemmy but a lot of my complaints here no longer appear to me occurring, so that's great news!!
