Just updated to 800 firmware and the latest DJI assistant and app and I am having issues calibrating the sensors through the assistant 2. I have tried re-booting my pc (win 10) and using option 7 but to no avail. The sensors are clean and when trying to calibrate, a green tick is showing on each of the small displays on the calibration screen. However in the app the calibration vision sensors are showing normal...am I safe to fly????
