I don't use Apple Music but I can confirm that Spotify skips for me from time to time. There were also times CarPlay connected, disconnected and connected again but that happened to me maybe 3 times since installing 17.4
Also, out of a sudden I stopped getting notifications from some 3rd party apps. At first I thought that might be app's fault but it's not just one app, it's multiple and even hard restart doesn't help. I turned off notifications, turned them back on but still nothing and I'm not sure why.
