I have a problem with linking my Apple Music

Hello Noahbrim,

Thanks for using Apple Support Communities. It sounds like you are trying to use Apple Music on multiple devices and having issues with an error message. Right?

If so, rather than signing up on the new device, try these steps from Access your music library on all your devices - Apple Support which should allow you to enable Apple Music on your devices where you are signed in with the same Apple ID.

1. In the Music app  on your Mac, choose Music > Settings, click General, then select the Sync Library checkbox.

If you don’t see this option, sign in to Apple Music using your Apple ID. You must be an Apple Music subscriber to access your music on your other devices using Sync Library.

2. To turn on your music library on another device, do any of the following:

• Another computer: In the Music app  on your Mac, sign in to the iTunes Store using the same Apple ID that you used on the first computer, then choose Music > Settings, click General, then select the Sync Library checkbox.

• An iPhone, iPad, or iPod touch: On your device’s Home Screen, tap Settings, tap Music, then turn on Sync Library.

If that's not quite what you are experiencing, let us know a bit more about what you are trying to do and which device you're using.

All the best.
