"When you try to associate another device that was previously associated, you might see a message that says, "This device is associated with another Apple ID. You cannot associate this device with another Apple ID for [number] days." Depending on when you associated your device with your Apple ID, you might need to wait up to 90 days to associate the device with another Apple ID.

This list of associated devices is not the same as the list of devices that you're currently signed in to with your Apple ID. You can see where you're signed in on your Apple ID account page."

If you don't believe that the device was used with another Apple ID within the past 90 days, confirm the Apple ID you're signed in to under Settings > iTunes & App Store is correct. If you need additional assistance, you can also contact Apple Support here:

Upgraded to iPhone14 Pro Max. Wife did too at same, same place (ATT)... Went through all the Apple ID/passwords/authorizing purchases/etc... At the end of all that, unknowingly I was logged in to MUSIC among other things with my wife's Apple ID and NO subscription to MUSIC like I did... This caused many other issues, but it took a 3rd level advisor to figure out I was logged in incorrectly with wrong Apple Id. Logged out, and back in using the correct Apple ID and things began to improve... Until... I tried to download from the Apple Music app and received:

"This device cannot be transferred.

This device must be linked to your Apple ID to play content saved offline. This device is already linked and cannot be transferred for 90 days."

I "removed" my old phone from the "Manage Devices" under Music/App store /Account/Account settings to no avail... It's now greyed out and say I have 22 days remaining and makes no sense to me...

Called Apple Support, reach 2nd? level advisor who tried everything to resolve, but concluded, "That's the way the software works by protecting copyrights. You need to wait 90 days"

WTF?!

I can't believe there is no way to fix this accidental issue. This forces me to cancel the subscription, because otherwise, all I have is another Spotify or Pandora (I already have Pandora).

Terrible engineering design!
