I am getting a forward vision sensor calibration error after the lastest firmware update.  Launched DJI Assistant to perform the calibration.  I keep getting a frame calibration error at step 2 despite tracking the ouitside of the screen frame.  Any tricks or best techniques to complete this step successfully?   Thanks

CLose and start the progam form the beginning and follow the instructions exactly and you have to keep up with the screen. Good luck!
