Why is my Apple TV not working?

Apple TV is not down globally. When Apple TV “stops working,” it’s usually a local issue with the Apple TV app, Apple ID authorization, or network on that specific device. Restarting, signing out and back into Apple ID, or reinstalling the Apple TV app fixes most cases.

"Apple TV is down"

Explain what you mean by that statement.

Check your Internet connection. Reboot your Wifi router. Restart your Apple TV.
