I everybody i ma using mi new mavic pro only a question where drone go in atti mode not opti mode, where take off in a Riom Large without wind drone go back and right not stay hold is normal Sorry i ma new pilot

If you are indoors and there's no GPS and you are withing VPS range and the sensors are within the limitations then it will use the downward sensors to keep it stationary.

Understand but in atti mode only altitude is Manson the problem is the drone drift back in optimimode is ok
