"Now playing" keeps defaulting to "on watch"
I listen to a lot of podcasts on my phone. I love being able to control them via "now playing" on my Apple Watch. But after a while (maybe a minute or so?) my watch defaults from "on iPhone" to "on Watch". I'm not playing the podcasts on my watch, only controlling them on there, so why does it keep doing that, & how do I make it stop? I want it to stay on "on iPhone".
I have an iPhone 12 Mini, updated to 16.4.1, & an Apple Watch series 7 (updated to 9.4.
I have "return to clock" set for 1 hour, which is the longest it will let you do. There's another setting regarding this that I can't remember now, but I have it set to the way that should make this work for me. Please help!
