Hard to isolate at what point this happened because there have been so many firmware updates, but sometime after May it seems that something is preventing the waypoint missions I create (or previous ones I have saved) from uploading to the Mavic. Using latest DJI GO4 on Droid Turbo2 and latest firmware on the Mavic.The intelligent flight mode lets you get into the waypoint function and even proceed to setting all of the waypoints like normal, however when done setting the waypoints and tap "apply" I immediately get an error telling me the "waypoint mission failed to upload to the aircraft." I tried over a few times. Landed, power cycled everything and tried again with no success. I also tried uploading a previously recorded waypoint mission from the same location and wouldn't upload that to the Mavic either. I tested some other I-flight modes like POI, etc. still work fine but the waypoint thing won't go. I wonder if anyone else has seen this issue.
