DH Mobile does not currently support the Mavic 3, Mini-2, Mini SE and the Air 2S drones.
We are waiting for DJI to release an SDK (Software Development Kit) for these drones. The SDK is required to enable 3rd party software support. Until there is an SDK for these drones, there is nothing Drone Harmony can do to integrate them.
We are monitoring the situation and are planning to start the integration of the drones as soon as the SDK becomes available. Unfortunately, we do not have an inside information on when this will happen.
