I just got my P3 today and successfully updated the drone itself. But when I got to the controller, I tried updating it by flash drive and also by micro USB from drone to controller, and neither gave me a blue light to indicate it was updating, even after leaving them plugged in for over 60 seconds. I turned them on then went into the Pilot app and it says that the aircraft status is normal, should I have anything to worry about? It doesn't say the controller needs upgrading anymore...
