My Mavic camera and drone seem not to be responding, however in the DJI app under aircraft status it states the gimbal status as normal. I cannot tilt the gimbal, when I turn on the aircraft the gimbal does not move. Also on the app, the camera view is black screen. I had this issue before and I formatted the SD card (which did not fix the issue alone) and then turned on the drone upside down (which fixed the issue). Now neither will resolve the issue. Please help, running newest firmware.
