It seems the Replies menu lists only those responses that are at least two days behind when you put in the response.
Edit: It may be that no Replies have been added on to my “Replies” menu since the change was done on my account.
Edit2: Ha, found them. So, Replies are to me. My responses are under “All Notifications”, but there does seem to be a delay in getting them.
Edit3: And I responded to the below link and I can’t find it in my “All Notifications”. So, any idea where I can find it in the new menu items? I can find the “heart” in “All Notifications”, but not my original response.
