Doesnt work

This app does not work. I have the at&t/direct tv bundle and no matter what I try, nothing works. It doesnt recognize my login info or it says loading and then the screen goes black. I know my info is correct because it works on my pc. Customer service is useless for this problem. Dont waste your time. Direct tv, you need to fix this app or stop using It as a selling point.
