After recent update my MaVic flash yellow during normal flight. It flash green ,gps strength 13to 15. But after taking off right after setting home point it flashes yellow . The flight is stable rc connection is good and everything is smooth. It flash green only after landing. No warning display. It flies as before . I have tried calibrating IMU, COMPASS and VPS. Nothing works . Everything is good . But I am worried about the yellow flash . The yellow flash slowly like the green one as before. Please help me
