This app is just awful! I can sign in and watch ONE episode of a show but after that I can't watch another episode or another show. It always gives me the "user not authenticated" error message. I've tried changing my password with my cable provider, setting up a profile, and the other things recommended on their website for this error but to no avail. The only thing that works is to Uninstall the app, then reinstall it and sign back in again. It is extremely frustrating!
