Cannot write posts from Jerboa

Since the last update, I cannot write or respond anymore with one of my accounts in Jerboa. The same account works as expected with Voyager and the web UI.

With the present account, I can post without problem (and I wrote this in Jerboa). I don't believe that I modified the configuration in any way.

I get the following messages in the other account:

• This account is not yet in a ready state
• This account (name of the account) is b... [cannot see more displayed]

The problem is not limited to any specific lemmy instance (same issue on feddit.de and lemmy.world).

Any idea what is going on here?
