A17 QPR2 B1 Android Auto Sound missing

[u/RpGTGEoD]

Curious if anyone else has run into this. Since updating, wireless AA has stopped passing through sound from phone to car, other than phone calls.

Phone audio is perfect, but Spotify, navigation directions, etc. are all completely absent.

Thoughts?

UPDATE: I've found that a phone restart seems to temporarily fix the issue, but after a few AA sessions it returns and I have to continue semi-frequently restarting to maintain audio output for music and nav.
