I spend one to two hours of my life trying to do a work around on this app. I kick the mark all as read button and everything shows clear. Close app and the icon still shows there are unread messages. For a fast look I want all clear so I know if I get a text. When this happens I have to start at the top and open each text wait 5 to 10 seconds close it. If that is the one showing the number but looking read it will clear. Right now the icon shows 6 unread messages.
