Description of Issue
ARC works completely as expected when I use my iPhone as a standalone player. Playback is snappy and album artwork appears correctly. If I plug the phone into the car and use Apple Car Play performance slows down noticeably. All the album artwork disappears or is shown incorrectly. Tidal over Carplay in exactly the same conditions works properly. There’s something odd about the way ARC and CarPlay talk to each other.
