Pretty sure I know what I clicked on since I tried several times but I was trying not to beat up on ancestry.
While I am here, I noticed that one tombstone photo was viewable as the main photo on an ancestor profile but when I clicked on it, it said it was attached to someone living and private. Obviously, no way to comment on that one in that tree. It used to be public but I guess no one copied it while it was public.
Actually, I found it in a different public tree so it could be commented on. Walking through that process actually answered a separate question that I had about media attached to the living in the initial tree.
