I am having the exact same issues. I cannot change anything on the screen of my vehicle through Google maps on CarPlay and it totally shuts down the google maps app or it will just freeze. I also cannot access screen time anymore and a few other features though the setting on my iPhone. I have wiped and reinstalled the software twice now and it’s all still the same! My vehicle is a 2021 jeep wrangler 392 just for the deets and my iPhone is a 14 pro max.
