She thought it might be on her end but I think it is really a quirk of the layout. When you click "Add comment" or "View comments" it does look like nothing has happened. But if you look closely, you'll see the scroll bar on the right side has changed. If you scroll down you should now see the comment box below! At least this has been my experience. Remember when on the Home page, you need to click on the post to read the whole article and comment.
I tried to switch it to a separate pop-up box in the settings, but I don't think that works with this layout. I have already gotten some comments, so I think it is working . . . I may have to add a note at the end of each post for this as a reminder. Thank you for telling me about your experience!
Good friends are like stars. You may not be able to see them, but you know they're always there.
