Thank you so much! I’ve had my watch for 4 months, I don’t know why I didn’t see that earlier. I have been going to the app switcher this whole time.

One other thing is the big (non knob) button brings up three apps and somehow I have it so now playing is always one of them. Can’t remember how I set that up though. (Doesn’t help when someone keeps texting me and I want to stop the audio.)
