First, find a wide open clear area to fly in. Preferably a large open field. Do several flights. If the issue goes away, return to this flight area and try it again. I can't explain why you say this seems to be occurring after a few successful flights in the same location. But you have the same issue as described above it appears. Here are your sat counts for both flight's. They are wandering all over.why does it not happen every time I fly the drone.
