App not appearing in CarPlay

I got a CarPlay entitlement and updated my app to use it. When running in the simulator I see it appearing to work properly. I then sent to my tester via TestFlight but he said after installing the new version he doesn't see it on his CarPlay device.


I have no idea how to even begin to debug this issue, especially since I don't have a car with CarPlay 😟


Any ideas?
