I recently went from Android where I had the ability to repeat most songs with Android Auto. With iOS and Carplay the back/repeat button is missing/greyed out on the Touchscreen and does not function when the physical controls are pressed. I have tested it and found that this feature works with Apple Music, Spotify, Youtube Music, Amazon Music but not Pandora. In order to repeat a song I have to unlock the phone open the Pandora app and press the repeat button. While driving.. Let me tell you that's a safe option.. I have young kids who want to hear the same song multiple times... Please add the ability to repeat a song through Carplay like all your competition already can.
