Shared audio output with Apple TV
I'm trying to use two sets of Beats Solo3 headphones for shared audio on Apple TV (tvOS 14.0.1) but they will not work at the same time. Each one will work alone OK.
Apple TV (4th generation)
I believe audio sharing works with the Apple TV 4K model, not earlier models unfortunately. Presumably this relates to bluetooth 5 vs. bluetooth 4.
