I have an Apple Watch 3, and only my AirPods and the Apple Watch speaker show up whether I use the control center or force tap on the music app song playing screen. From googling around, I got the impression that I should be able to see wifi based airplay devices. My iPhone sees all of them on my network, I have 2 Apple TV's and my Sonos bridge listed as Airplay options on my iPhone, but my Apple Watch doesn't. I've tried restarting, no luck. Am I correct that my Apple Watch should see wifi airplay devices?
