As a science editor, I have learned so much in the many hours I have spent every day on this app. But just recently I have become unable to read the comments because I am not, strictly speaking, a "health care professional." Previously I was unable to make my own comments (which was fine with me) but was able to read others' comments. Now all I can do is look at the pictures, so the app is no longer either fun nor educational for me. This is very disappointing, and I don't understand the reason for this new, but unannounced, restriction.
