Having trouble replying and writing on my post.

Hi

Why can't I post anything on the post I posted myself? I'm trying to reply to comments and they seem to post, but as soon as I reload the page my reply disappears. I also can't post additional information on the thread. What's going on?

Here's the post: https://community.adobe.com/t5/lightroom-classic-discussions/the-export-dialog-box-doesn-t-appear/td-p/15070183
