During my last flight, I received two "full-stop" obstacle avoidance warnings when there was nothing around.  In both instances I was about 18-20 feet above the ground (once over sand and once over water), flying forward at ~13 MPH.  I was on a beach, so there was a persistent wind and a bit of ocean spray, but nothing that would have--at least in my mind--set off the sensors.  In both cases, I had a pretty aggressive forward pitch, and I'm wondering if the sensors are sensing the ground from about 20 feet away and causing the avoidance to kick in.  Has anyone else had this happen?

Where was the sun? A setting sun is sometimes a sensed obstacle and stops my Mavic Pro.

In my case, high in the sky and well hidden behind clouds.  When I get home today I'll post the clips of the stops.

May it be the sunlight reflected by the water? Like Folkestone mentioned above, the strong light might activate the obstacle avoidance. You can check back the video and see if it is the case.
