I am using a Mavic Pro 2 (last firmware applied), piloting with iPhone 11
For the last couple of flights I have been having some problems with my drone.
What I have been seeing are 2 things : the drone seems to deviate from its trajectory (eg I want it to fly in a straight line whereas it seems to pull towards the left). It was a nice warm day with very light breeze.
The other problem is as it progresses, the drone slowly descends on its own.
The only warning messages I have had during the flight is “obstacle avoided”. That could potentially explain when I was making it pass through a path in the middle of the woods; however when I do a test with active track it seems to work smoothly & seamlessly.
I did some further tests to see what was happening. I went out in an open field and the drone was flying more or less straight but it was still descending. There is no obstacles and no weak signals. Moreover the altitude is giving me really strange readings. Sometimes it would say I am in the minuses (eg -1.5 meter) but it was not possible!
In my last flight, I was in a wide empty building (like a hangar). And there I have had some very odd behaviour and readings. According to the drone, I had reached the maximum altitude (I was only at 3 meters and there was room to go up), there was an obstacle that was avoided (there were no obstacle). The altitude readings were completely off and nonsensical. (I will include the log below)
At one point I saw that the drone was deviating towards to the left so I corrected it by commanding it to go right but it did not respond. It went completely nuts, took up speed and made a sharp veer to the left and boom, hit a plastic window and fell.
According to flight log it was saying it was avoiding an obstacle but there was none!
Here are the 2 separate flight records :

Has anyone had encountered similar issues?
Does anyone have an idea of why this is happening?
For info, I calibrated both the compass and the IMU but still issue persists.
Thanks for your help & support.
