Apple music has been glitchy and CarPlay is unsuable since going to ios 18.

When I lock the phone Apple Music pauses, when I unlock the phone Apple Music pauses. When using CarPlay, or not being able to use in my case, the sound is almost mono. I also can not get it to connect or play over the speakers most of the time. When I am able to use it, the sound is mono when the phone is mono and stereo when unlocked.
