So hears the deal , My Anafi decided to take a swim in the ocean after doing the latest battery update . Total power failure and the drone was lost , not recovered . I approached Parrot about possible replacement under warranty and the first thing they requested was the flight data from that flight . As we are all aware , the anafi doesn't log the flight data until the drone has returned and motors stopped . So when they are lost there is no data recorded . When I explained why i couldn't provided it , they kept coming back with " they need the flight data " . They eventually denied my warranty claim, which I am really disappointed about . They have set up the flight data system so they can dodge warranty claims , this is so dodgy . I have owned 3 parrot drones , this was my last . Time for a DJI .
