I have a GL300A controller and it will not update to 1.9.3 for some reason. It is stuck on 1.9.2, even after I refresh the firmware to 1.9.3 within the DJIGO application. Is there another way to update the firmware? No update messages appear when it is connected to the Phantom 3 Pro. I've tried many of the various button combinations already.
