After updating to the latest firmware, my P4 is doing some weird stuff in manual and auto take off. When manually launching, it looses power about 2' off the ground regardless of what I'm doing with the sticks. It begins to drop and then after a split second it recognizes my input and lifts up until I stop it. When I do the auto take off, a similar action is visible. It does a funky yoyo dance and then goes up to the hover position. Very bizarre and not comforting. Before updating, I had about 50 flights on this P4 without any issues. I did a basic cold IMU cal, but not a sensor cal w/ DJI Assistant after updating firmware and DJI Go. Will do the sensor cal now.
I should add that the same take off behavior is also present when using Litchi.
