I've tried twice today to do an IMU calibration on my P3P. I've left the drone outside in my car for about an hour, it's currently about 20F outside. I bring the drone in, have my controller and DJI Go app running. Turn the drone on and quickly run an IMU calibration. After about 3 minutes, I get "IMU calibration OK". I do not see the status bar move. It stays at 0%. Thoughts?
