@dpstjp — Thank you for the input, it is greatly appreciated! Although iOS is pretty aggressive about putting Roon to sleep when it’s in the background, we’re looking into how to make this smoother in the future.
@Joost — Thank you for the follow up information! Can you please tell us more about your system and network as described here? Also, just to verify, are you certain that your iPad is connected to WiFi when this issue is occurring?
