When using Bluetooth audio in my mark7 VW GTI with my Pixel 3 on Android 11 the GTI can no longer receive any metadata other than the track positon. On-screen and steering-wheel controls that used to work to skip, pause, play, etc. all are unresponsive. This started at some point a year ago probably after an Android system update. Unfortunately the car does not have built-in android auto integration. My wife's LGthinq 7 has no issues.
Multiple attempts at resetting the Bluetooth settings on my phone and the car and repairing have not fixed the issue.
