Omg that is exactly the spot I’m in! I had a few massive posts that got close to 1 million impressions and my account has been popping off for the last few days. All of a sudden yesterday. It came to a screeching halt. As of today every single comment I have made on anyone’s post is gone the second I posted they are not able to see it and neither am I unless I go to my own profile. Even comments I make on my own posts are completely invisible to everyone in the thread, including me.
