Hey there @Pyrdogs, I hope you are doing well.
I am wondering as well. I have been unfortunate when it comes to getting in to the Android Auto beta. I was excited to hear that the new design is now out of beta yet I've received two Android Auto app updates and still have the older design. Based on how Google handles the roll-out of new app designs/features, I wouldn't doubt that it is a staged roll-out and will land on our beautiful Galaxy's soon.
Take care.
