I'm trying to create a Media Services (MusicKit) key to use the Apple Music REST API from a server-side application. When I navigate to Keys → (+) and select Media Services (MusicKit), I receive the error: "There are no identifiers available that can be associated with the key." I've already tried the suggested fix of registering an App ID with MusicKit capability enabled (Identifiers → + → App IDs → App, with MusicKit checked under App Services). The identifier shows MusicKit as enabled when I view it, but returning to key creation still shows the same error. Steps taken: Registered a new App ID (com.turnkeycorrections.musickit) with MusicKit capability enabled Hard-refreshed the Keys page after registration Verified the identifier saved correctly Account details: Apple Developer Program (Organization) Role: Account Holder / Admin My use case is server-to-server only — I just need a developer token to call the catalog search, charts, and artist endpoints. No user authentication required. Has anyone resolved this, or is there a step I'm missing to unlock MusicKit key creation?
