Apple TV won't let me sign in
I bought a new iPhone and received a year of free Apple TV. I have an Apple TV device that is a couple of years old. I keep trying to sign in. It takes my user name and password then it wants me to enter a 6 digit number after the password. The system sends me the 6 digit code but when I enter it after my password, as instructed, it just keeps saying it is incorrect. How do I fix this?
