[iOS] Apple Music Authorisation vs Media Library Authorisation

In order to access the User's Apple Music Library, I need to request authorisation from

SKCloudServiceController.authorizationStatus()


Also, there is another authorisation option in MPMediaLibrary.


I need to be able to access both user's library and the Apple music library.


During my testing SKCloudServiceController.authorizationStatus() returns authorised when MPMediaLibrary.authorizationStatus() is authorised and vice-versa. I need to know, if checking either of these is sufficient enough? Are there any situations where authorizationStatus from both places might be different?
