I haven't flown my mavic in about a month. This morning I went to fly it and the controller was dead. After charging it I went to turn it on and nothing happened. When I push the power button it shows it is 100 percent charged but when I go to hold it after that it never turns on. Had this happened to anyone else? Also I've had about 6 months so I know how to turn the controller on, I know someone was gonna explain the sequence for the power button.
