My gimbal wheel stopped to work on controller (not smart cont.) while I was flying my mavic 2 pro. I returned to home point and since then I am not able to control my gimbal with the wheel on my remote control. Even when I go to gimbal callibration blue lines are missing while I am trying to move it from right to left. I didnt upgrade the software before the problem occured. What should i do? is there anything I can do before I buy a new controller or I take to the service center? Thank you in advance.
