I'm having the same issue. After my token expired, I've generated a new one and tried to authorise, but got no result. After successful authorisation in the app, onActivityResult always returns USER_CANCELLED. Last update of the "Apple Music" app itself was in 23rd of March, maybe that update broke something.
