How do you silence the camera shutter sound when taking a photo with the Mavic Air 2? I've already silenced my iPhone (turned the side switch to vibrate with the orange showing) and when the controller is not attached, there is no shutter noise when I take a photo. But once I attach the phone to the controller and take a photo, there is a loud camera shutter noise. It's very annoying and attracts too much attention. Also, how does one lower the volume on the controller in general, like when the voice tells you "the home point has been recorded..." etc.?
