Uverse App for XBOX one - DirecTV

I have tried several times to use the Uverse app on my XBOX one. Every time I open the app, I am asked to redirect to a browser in order to link the XBOX with my att account. I click the redirect button and it opens the browser to the Uverse Webpage where I confirm that this is the account associated with my service. I have a ether net connection so I don't think it'd be due to WiFi. HELP
