Just a heads-up as many users in that thread are reporting Android Auto issues with their Pixel 8 and 8 Pro phones, and the response by the Android Auto team there is to file a bug report.
Do you also encounter issues with Android Auto with the Pixel 8/8 Pro?
I’ve had issues with it every time I get a new device. I don’t have the 8. I have a 7 Pro but I had issues with that at launch and the Note20 Ultra prior at launch and the Pixel 3 at launch. I’ve typically had to wait a couple weeks after I buy it for everything to get figured out. The only one I’ve consistently had issues with is my 7 Pro. It’s almost like it won’t work with my older car anymore. It works sometimes and then other times disconnects and refuses to connect. I blamed it on tensor(uneducated guess) but it’s been a year now and my issues have mostly disappeared.
I had a P7P as well, and I also had no issues due to the phone (but the USB cable that came with the unit was shit).
