Sounds (beeps) & haptics not working anymore when in 'wrist down' mode (always on display)

Our watch app, Regatta Timer, is a specialised countdown timer for sailing competitions. It is crucial that the beeps & haptics continue when 'wrist down' on alway on displays. We tried to enable this by adding 'background mode' but that only works in the Xcode Apple Watch simulator, not on an actual device with always on display. Any idea how we can get this working also on the Apple Watch device?

In ContentView.swift we currently added this code:

WKInterfaceDevice.current().play(sound)
}

but that doesnt work - regardless of adding , phase == .active` or not.

STEPS TO REPRODUCE

  • Install on an ACTUAL DEVICE with always on display
  • start the countdown timer: beeps & sounds are OK (each minute,...)
  • do 'wrist down': the countdown timer continues on the dimmed display, but the sounds & haptics stop working until you raise your wrist to wake up the display.
