This is still a prevalent error and mayor issue imho.

Edit: even worse, when I’m trying to post a comment that gets blocked by this error, the only real option in the UI is to delete the post unless I want to endlessly retry.

However, sometimes when I choose delete, I’ll later visit the thread and it says “Deleted by user” with my username. Well dough I was never able to complete the submission of my post in the first place!

This is a critical interaction bug.
