Has anyone used the newish power button app to restart or turn off your phone? I love the idea, but it isn't working on my Icon. When I hit restart, I get an error message telling me to "Can't do this action. Make sure Device Portal is enabled with Authentication (off)." However I turned these 2 items on and still get the error message. At the moment this is worthless I just did a soft reset and it still doesn't work. Time to delete.
