My thinking is that while the app might not always request the compass calibration, it is such a simple and quick procedure that there is no harm in doing it anyway. DJI recommends compass calibration for any drone that has been transported over...
The incident in the title only takes 2 minutes of the 18 minute video.
There's either a lot missing from this video, or it's fiction and clickbait.
It simply says that the drone was siezed, with no explanation as to why.
There is no prohibition...
