Update: I stupidly tried everything EXCEPT rebooting the phone. After I shut it down to disinfect everything works fine now.I have a 2018 Essence (old UI) and using Android Auto (Pixel 3a XL)....
In the past couple of days, Android Auto has not been working properly. When I long press the steering wheel voice button, I used to be able to access Google Assistant for voice commands.
Lately when I long press, the music quiets but I never get the tone to indicate I can speak the voice command. I also don't get the search bar in Waze. And if I press the microphone at the bottom of the screen, I get the Buick voice control (not Google).
I've swapped out the chord (yes, data capable cord) and been through multiple start/stop cycles but the issues have not been resolved.
If you have the older UI (red needles), can you check to see if you are experiencing the same issues with Android Auto? Thanks!
