I have the DJI Air 2 with the RC 231 controller. I was in mid-flight when I "panned right" with the joystick and the drone kept going in that direction even after i let go of the joystick. I safely landed the drone. I went to recalibrate the controller and I couldn't get the right joystick to calibrate for the Left-Right calibration. I've called DJI, no help there. I went to the DJI assistant on the computer to do a reset of the controller and it wouldn't give me that option. My battery is fully charged and the firmware is up to date. Is the controller completely broken at this point?
