Cannot login in to Apple TV.
I am trying to login in to one of the AppleTVs in my home but I get this message:
"Unable to sign in"
The account name or password was incorrect. Please try again. I have done that several times and each time I get a verification email with a 6 digital number that I am supposed to use but there isn't anywhere to enter that number with this appleTV. All other AppleTVs (1-4k, 3-Original versions) are currently working.
What to do now?
Windows 10, iTunes
