FYI, while working on part 4 of my tutorial series I came across a strange behaviour regarding DJIFlightController.startLandingWithCompletion and posted a question on StackOverflow: https://stackoverflow.com/q/66101006/1065468

Any hints highly appreciated.

Maybe you can contact the DJI for help directly.

Thank you! I have send DJI Dev Support an email and they already replied.

I am in the process explaining, that I just need to know from where in the SDK this warning message is coming from.

As I have written on Stack Overflow already, the message does not come when I change ground below the drone with a carpet that has better contrast (flying indoors). I am not looking for a solution though for the message to not come up any more.

I just want to know which class is responsible for this message.
