Hi, I recently observed that my Mavic Air 1 is sometimes unable to maintain low flight altitude [3 ~4 m (10 ~ 13 ft) above the ground] even under low to no wind condition. I use this height for active track. Sometimes the drone would be unable to cope and would descend to the ground and then ascend again. Not an issue if I am flying higher [>10 m (30 ft)]. Has anybody experienced this and any suggestions for managing this issue?
