Apple music not working on apple tv 4k

Hello,

Thank you for using Apple Support Communities. I see that you're receiving an error about your Apple ID region when trying to play music on your Apple TV. You've come to the right place! I'm happy to help.

If you haven't already, make sure the region used for your Apple ID matches your billing address and where you currently reside.

If the issue persists, restart your Apple TV and test the issue again. Restarting can resolve many unexpected behaviors.

Possibly your Apple TV is set for a different region than your other devices.

What matters is the (active) Apple ID account for the iTunes and App Store (which has a region attached to it), and the Region setting of the Apple TV set top box.
