i have just replaced the gimbal and camera on my mavic 3 and i am trying to do the python calibration but when i plug the drone in it doesnt come up under the COM ports tab in the device manager. it shows up in the file explorer though i have tried with my air 2s and it comes up but not with the mavic 3. anyone know how to fix this?
