Precision Flight is nice and simple, works right out of the box w/ CS, MapBox and P4V2.
The MapBox issue w/ PIX4Dcapture is now understood - app version 4.5 is necessary for the CrystalSky due to the older Android hardware - app version 4.5 relies on "Legacy Tile API" for which MapBox stop supporting late 2020. PIX4D has this well documented.
Workflow will be modified to plan mission in GoogleEarthPro and import KML file to PIX4Dcapture inclusive of base map, what's wrong with that?
Precision Flight lacks 3D flight planning is the only rub for my situation.
All this can be solved w/ iOS device such as iPadPro but the CS (1k nits) works nice and I use it with M2E / DJI Pilot but the
P4PV2 is a better workhorse for mapping...fyi.
