Apple TV is not recognizing my apple password
I have an old Apple TV (Model MC572LL/A, software 6.2.1 (6698.99.50.41)I believe it's from 2010. It has been updated every time there is an update.
I have a 2016 MacBook Pro, and an iPhone 8.
The Apple TV is not recognizing my apple password. I have tried to change the password, and it has not worked. It works on my phone and my laptop fine. It's driving me crazy. I end up not being able to watch movies on my TV, but instead on my computer.
In addition, sometimes AirPlay works and sometimes it doesn't, when I'm trying to transfer my computer screen movie to the TV. This is a problem especially with rented movies.
Any suggestions?
