At the very bottom of the comments area there are options written in very faint print. I’ve always seen it say: Comments Reply Edit Support Not Support. Today after a failed attempt by my fingers to write a comment I tried to edit it. The very faint print now said: Comments Reply Added Support Not support. I was unable to edit my garbled comment. Upon continuing to comment on other posts I find that the screen changes continuously between the two screens. Is this a malfunction? I’m someone that really appreciates being able to edit my comments.
