I'm fairly new to owning the DJI Air or for any drone for that matter. My Air was working fine but turned it on today and it was moving slowly when going forward and backwards, up ,down and turning is normal. Downloaded the dji assistant 2 and updated the firmware/calibrated the drone. I then tried to calibrate the controller with DJI assistant but won't recognize the controller, the calibration for the controller in DJI app, keeps telling me to push the two joy sticks to the limit (100) several time and I do but it never gives me the option to finish the calibration. Pretty bummed out now , hopefully won't have to send the contro;;er in for repair or buy another one, any help would much be appreciated. Thank you in advance.
