Thanks for the reply! I have also tested AVAudioSession with .playback + .mixWithOthers on watchOS. That works for mixing my metronome with Spotify while the metronome app is in the foreground, which matches the behavior I already see on iPhone. However, on watchOS the metronome stops once the app goes to the background, while longFormAudio keeps it alive but then conflicts with Spotify. So this seems to be a watchOS-specific limitation rather than a general AVAudioSession limitation on Apple platforms. It would be very useful if watchOS supported a way to combine background audio persistence (longFormAudio) with cooperative mixing behavior (mixWithOthers) for lightweight apps like metronomes, cues, or coaching audio. Is there any way I can formally request this feature other than the FB22273077 I have already submitted?
