ATV 2 step authentication login loop
I have the last model ATV, specifically:
Model A1469
ATV Software 7.2.2 (8015)
After installing OSX 10.12.4 my ATV wont authenticate --- it is stuck in a login loop.
Steps to reproduce.
1/ Navigate to purchases on ATV.
2/ ATV presents iTunes store login.
3/ Submit Apple ID.
4/ Submit password.
5/ OS X receives "Your Apple ID is being used to sign in to a new device" and issues code.
6/ Enter login code.
7/ Authenticating.
8/ Returns to 3.
This is infuriating. I am locked out from watching content I paid for while illegally obtained media would play instantly.
