apple ID in second hand apple tv
So, I got this apple tv used.
In users and accounts theres only my apple ID
USERS
Current user: me
Apple TV Accounts:
icloud: me
game center: me
Mine is the only aco anywhere in users and accounts. However, few times a month it says "apple id verification" insert password for previous-users-apple-ID@icloud.com
Whats causing this?
What can I do?
