Yes, after updating the latest firmware all our waypoint flight plans are not accessible! However, if you look into the RC2 internal storage folders at:
This P
C\DJI RC 2\Internal shared storage\Android\data\dji.go.v5\files\waypoint
All the waypoint folders are there but are not visible via the RC2 waypoint function.
Here is what I found out: DJI changes one of the namespace
from
xmlns:wpml="http://www.dji.com/wpmz/1.0.2 to
xmlns:wpml="UAV.com - Your source for the latest news on uninhabited aerial vehicles.
in the latest waypoint wayline markup language -wpml without updating the spec in its Cloud api.
Not sure this is the culprit but,
So far the only way to get back my old waypoint flight plan is to recreate a dummy one, copy and rename the old kmz file over.
This is the only way at this point until DJI gets its act together!
