Flight mission planning and execution in iOS Future updates of Drone Harmony for iOS will include numerous key additions, such as the 3D interface. Moreover, missions can currently not be executed in the virtual stick control mode, meaning that some drones (e.g., the Mavic Mini, the Mavic Air 2, and the Spark) and missions that include panorama waypoints, are currently not supported. The support of this flight mode will be included in an upcoming update.
