In my Android device application uses CM Locker. On the device Sony Xperia M5, Android 6.0 mi from the lock screen display album art. On older devices M2 Xperia Android 5.1.1 my album art display. In the past, however, I did not have this problem, I do not know if the latest Android updates and application updates from Spotify. Does anyone advise if I can do something to me album art appear on the lock screen, CM Locker?
