Ok I changed my password after fears of a hack. I could get in once in like 5 attempts on the website but would randomly be kicked.
I made a backup account and added it as a mod in the one community I’m in just in case but it seems better now.
So changing the password may work. Or maybe the website was just being funny for a bit.
Edit: that seemed to fix the website but the app is still crazy buggy. It logs out when changing view to posts or basically any action like trying to comment.
