Does the small power button on the side actually work? When I have it plugged in, it messes with my dreamlink receiver so I have to unplug the usb-c power cable from the classic. I can't get the power button to shut the box off totally. I have tried holding for 3-5 seconds and still nothing. It just turns the box off and on like the power button on the remote, or is that all its supposed to do?
