Hello, I've been having issues with the buttons on the notification bar, it only works once then after the album art animation (after pressing a button) everything disappears, it goes all white except the album art. I have to open the app to just to change tracks. This is also the case with the official player. I'm guessing it has something to do with the album art animation. I'm using this player on my LG K10 running on marshmallow... but it works fine with my Xperia z1 on lollipop.
