When I create the post, it gives me that error, signs me out, and removes the user from my user list.
Edit: I can create a post here with that account while on my pc browser.

I can’t reproduce it reliably, but it only affects my .world account. Maybe that’s a fraction of a clue. Sometimes comments fail to post, then work fine for several attempts, then fail again, never with other accounts. I’ve tried adding/removing the account. This video shows it failing and working across multiple accounts, but no errors appear. (Sorry if this isn’t helpful at all.) https://files.catbox.moe/w026ss.mp4
The latest update doesn’t have a fix but it adds a little error icon when a comment fails send. If you tap the icon it will show you details of the error. You can give the update a try and see if it uncovers any additional clues.
