Ok, I answered to his answer, resulting again in 'a comment to comment'. But my answer doesn't appear in my own TL/Activity. Probably also not in his TL. I wonder #IsItJustMe or do many 'comments in reply to a comment' will remain unseen. You have to notice it in your Meanwhile panel on the right where it might get lost in unimportant stuff.
