Thanks for the feedback, Luis. There DJI SDK still needs a bit of work on its connection management and taking over the camera connection from the DJI Go app.
The Go Home button is used to record the point to return to if you are part way through a mission. If you push that first, make sure it is recorded and then flip to P then you are in complete control. Most people will just let it get most of the way down and then take it over.
As an FYI: you can steer the aircraft while it is autolanding to make it land as smoothly as you want. Left stick up will slow (stop) the automated descent.
