Hi. Reading the Litchi user manual it seems that I should be able to do a Compass calibration under Settings and Aircraft. On the screenshot from Litchi there is indeed a Calibrate Compass option. But on my App (iOS) I cannot find it. Tried with both P4 and P3S. Any ideas? I have Litchi Version 1.6.0 I also notice that even with my Standard the Litchi App claims to be able to set Preview Quality and Transmission Channel, functions not available in the DJI Og app for Standard users. Is this normal?
