Sign-in issue with TV provider
I have the new Apple 4k TV. I am having trouble signing in to certain apps. I first get a "success" message followed by "no authorz" when I try to watch something. I believe the problem is that I am signed in to ATT Uverse under a subaccount. I need to sign in under my main account in order to get authorization from the apps. Apple TV automatically keeps signing me in the same way - under my subaccount. How can I get the device to let me re-sign in to ATT Uverse as my TV provider under my other account?
