This used to not be a problem on ios 9. Then on ios 10 anytime my phone connected to Bluetooth not just on my car it would deselect shuffle play and repeat playlist. Then I downloaded ios 11 public beta 7, and yes I know it is only the beta, but whenever I try to skip a song anytime even off of Bluetooth it would deselect shuffle play and the repeat button. I have uninstalled and reinstalled and re-logged and everything and this issue won't go away. I think it is a bug for ios 10 and 11. I don't think this is a popular issue but it hasn't been fixed.
