Hi, I just bought a mavic 2 zoom, and every time I fly, the status light blink green (normal) , but now and then they blink a couple of times red and then return to green. I've check everything, the sensors are OK (IMU and compass), I've done the IMU calibration, but this happens every time I fly. I get no warnings on the cellphone screen. Is this normal or my drone is in danger of crashing?
