Went out to fly my Mavic Platinum Pro today. Got everything set up and plugged in. Tried to turn on controller - screen flashed "battery at 95%" then turned off. Tried several times with same result. Interestingly, although the drone battery is near full charge, I couldn't get the drone to stay on and connect either. I must be doing something (or not doing something) simply stupid, but I can't figure out what it is!
