So I am fairly new to drone flying. I have a Mavic Air 2, today while on a flight around my home I hit the RTH button and my drone responded by climbing to a height of nearly 700 ft before I could gain control, cancel the RTH command and navigate it back home. The battery was about 70% when I began my flight and at about 30% when I activated the RTH command. Any thoughts of what might have happened?
