Mods, a couple times I've gotten a comment on one of my answers (shows up in my Q&A) but when I go to read it it doesn't show up. Why?
It's because it was flagged and removed. It could have been offensive, nonsense or a number of other things. But don't blame the mods. If ask users see something offensive, we can flag too for the mods to review.
That's happened to me too. It's kinda irritating.... (Not a Mod..Sorry!)
That happened to me as well. I think it's happening to a lot of people.
It's been happening to me a lot tonight. The signal appears on the upper right but there is no update. I did find that if I keep checking it finally shows up Usually it's a comment to a comment.
