The app is dysfunctional, and it has been so for some time.

1. You cannot respond to someone who has wanted their comment to appear on their own profile. You have to sign onto your desktop in order to do so.

2. It's difficult to find someone's comment if they are too far down. Sometimes I have a lot of comments. Around about the 10th or 11th one, I have to sign into my desktop to be a ble to read the the comment.
