Thanks for checking. When you say "main screen" are you referring to the HUD? Or one of the other screens (behind the steering wheel or on the center console)? The problem some of us are experiencing is specific to navigation instructions in the HUD. The other screens are working as expected.
Good sleuthing. I'll file a similar request.
I guess this is a motivation for me to finally try Waze. Do you need to do anything special to get Android Auto to default to Waze instead of Google Maps?
Both my wife and I are also experiencing this issue and just noticed it in the past week on our Android phones (Pixel 7 Pros).
One potentially useful data point... The issue impacted my wife one day later than me, so that makes me think it is likely an Android or Google Maps update that was...
