So, I have my Apple TV (4th gen) set up in HomeKit in my living room. Then I have my old Airport Express set up with some speakers plugged in in the dining room. When I say, "Hey, Siri, play Bruce Springsteen on all speakers," music comes out of the dining room speaker, but not the Apple TV. This is what the playing screen from Control Center looks like on my iPhone: No idea why this isn't working. Any ideas, hive-mind?
