Has anyone else experienced a RTH that wasn’t initiated by the pilot or a low battery? I have had it happen twice now despite a >90% battery charge, in Normal flight mode, CAVU conditions, about 10-20ft above the ground.

I’m trying to figure out what went wrong so I can understand if the FPV is having a negative flight event or it is just a software bug or what exactly.

Yes.  It is happening to me every flight now.  I am taking it back to my dealer for care servicing.
