Hi dang, my mistake on the diagnosis, then. I thought that because I saw an error message that said " Sorry, we're not able to serve your requests this quickly." and after that the edit button was no longer visible for me on my comments. I often access this site through a ProtonVPN connection, so maybe there was some suspicious IP address heuristic involved?

The edit button is still not showing up for me, though. Do you have any idea why that might be or if there's something I can do to fix it?

Edit: Was there a thread-level edit ban or something? Because I can now edit this post.
