Mine is doing the exact same thing while flying in sport mode. Ascends on it's own and decides to land when I'm dropping down. It caught me off guard a few times now. I'm using the new DJI Go 4 app with an Iphone 6.
I should also point out that my mavic (while in sport mode) would throw up a warning as if it was sensing an object in front of it - even though it was flying in clear and open space.
were you flying directly into the sunlight? If you were that would affect your forward sensors.
