Hi, I did many hand launch/land Air 2 recently while was using it in the mountains. To hand-land I hold my hand below the drone and press 'land' icon on the phone. I've noticed that it often warns that it isn't safe to land and shows Yes/No confirmation dialog, so confirm landing and everything is ok. But sometimes it just shows cannot land error (without any choice, just OK button). When such error is shown and how to avoid it? I hand land the drone in normal/tripod mode, is it helpful to do it in a sport mode?
