@jj I fixed it in akkoma (will be in the next build), don't know if it's the exact same problem you're seeing but probably same type of bug, a problem decoding the session's account (in the Mastodon API it's CredentialAccount which has more info than other users' accounts), which is also why your account avatar isn't showing up at the top left like it should). In the akkoma case, there are some extra fields defined by pleroma but akkoma and pleroma differ a little bit.
