Getting a USER_CANCELLED token error while trying to authenticate using Apple MusicKit SDK

The exact same thing just started happening to me as of yesterday evening. I even reverted my code back to a previous commit just in case and the same thing is happening.

Yeah, I'm still stuck on this too. I keep getting the same error every time I try to authenticate(with this app, old versions, sample code) to apple music on my phone ever since that error happened first. :\

I'm having the same problem, on two different phones too. happened to me after I accidentally deleted apple music on one of the devices then reinstalled might be related, mind posting your code? Here's mine:

private void authenticateApple(String token){
  Intent intent = authenticationManager.createIntentBuilder(token)
  .setHideStartScreen(true)
  .setStartScreenMessage("Sign In")
  .build();
  startActivityForResult(intent, REQUEST_CODE_APPLE_MUSIC_AUTH);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  super.onActivityResult(requestCode, resultCode, data);
  if (requestCode == REQUEST_CODE_APPLE_MUSIC_AUTH)
 {
       TokenResult result = authenticationManager.handleTokenResult(data);
       if (result.isError()) {
            TokenError error = result.getError();
            Log.e("ERROR", "error:" + error.toString());
       }
       else {
            editor.putString("music_user_token", result.getMusicUserToken());
            editor.apply();
            read_playlists();
            }
       }
  else
     {
       super.onActivityResult(requestCode, resultCode, data);
     }
}

I posted the play code also because I was able to play from this initially. Just wanted to check if I missed something when the app was shut which is not letting me connect again

Never used flutter but seems like we have about the same code, My code also worked initially so no idea what could have changed

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.

Yea I agree, I filed a bug report in the feedback assitant, I think we should all file though so that the bug gets enough attention since this can basically break an app

That is a good idea. I still have not been able to resolve the issue at this point. Seems like we are all going through the same issue.

Yep, makes sense. Filing one too. Hoping this gets resolved soon.

Agree 100%. I'll file one as well. Have you heard back from them?

nope

I and Aditya contacted support, and were directed to file a TSI. When we try to file a TSI it complains that only ios platform related questions are supported. How have you guys contacted them? Anyone has heard anything yet?
This bug has broken our application.
