CBS All Access login
I have a subscription to CBS All Access - Limited Commercials. The subscription is current, and it has been working fine for the past 6 months. Suddenly however, I am not able to watch any content on the CBS app, I am prompted to sign up or sign in. My only options for signing in are through my TV provider or with CBS All Access. Again, my subscription is through apple, and it is verified as current in my settings. I have tried restarting my Apple TV, and I have tried deleting and reinstalling the CBS app. Neither of these attempts have been successful. Everything worked fine as recently as Dec 18. Now it doesn't. Any ideas on what went wrong and how to fix it?
