Getting TV Provider "Sign In Error" for Cox cable login after Cox required two factor authentication
I changed my password and enabled two factor authentication for Cox. Then, I got an error on my apple devices (phone, ipad, and apple tv):
An error occured while attempting to load details. The TV Provider is no longer available. Sign Out
I click sign out and when I try to sign back in, I get "Sign In Error"
This happens on all apple devices. I tried to log into hbo max and also got the sign in error. However, hbo max displayed a link and activation code. I went to the link on my computer, put in the activation code, got redirected to the cox site, logged in with 2FA, and now hbo max is working.
It appears to be a problem with Apple. I'm never prompted for 2FA for cox. The login just fails.
Apple TV 4K, tvOS 15
