Litchi, though has a known prblem with Mavic Pro and P4P. I have done countless missions with P4 which have been awesome, but both of these mentioned birds behave erratically.Using a combination of Google Earth and Litchi Mission Hub gives you great ability to plan your mission with waypoints on the higher elevations. BUT, best of all, when you open you mission on your tablet/device you can set your waypoint altitudes to be RELATIVE TO GROUND, instead of relative to HOME. Don't freak out if you see some waypoint elevations with negative values. It just means the terrain is sloping downhill from your home point. Really nice for shooting video while keeping the aircraft a fixed altitude above ground.
Used that feature on this flight to stay 45' AGL on outboundleg.
