My Question or Issue

When I add track to queue using method ( 

- (void)enqueueTrackUri😞NSString*)trackUri callback😞nullable SPTAppRemoteCallback)callback;

). There is call back with incorrect results, because in any case (song was added or not), result of call back always not nill, and error of this callback is always nill. And because of this I can not catch error and retry operation if song is not added to Spotify queue.
