Upgraded firmware today, both DJI Mavic firmware and Litchi update. Was having trouble before and does not appear that there is much improvement. Still have: 1. No focus control on RC. C1 switch set to centre focus. When depressed, it momentarily focuses, then defocuses. 2. Software locks after completing mission with video continuing to record after trying to shut off manually, even after landing. 3. Litchi will not centre on POI. Always seems to be off, either left or right and vertical is not where it is set. Aircraft seems to be yawing properly but pitch angle on the camera is off, on occasionally tilting up, then down erratically. I have tried both Focus POI as well as Interpolate. 4. Live video feed is stuttering and sometimes locks, then starts again. 5. Often will not load mission at start of flight. Stalls on load page. I use an I-Pad Air and seems to work with DJI Go 4 pretty well. Litchi has just not done their work on the Mavic Pro App.
