My Question or Issue

 Voice command has stopped working on android auto, I think since the Oreo update. When I ask to play a song it just says 'sorry I don't know how to do that' or 'im not able to display search results in the car' depending on how I word the request. It worked fine since we got the car 9 months ago. This is I must have in android auto so please fix asap.

Thanks
