I purchased the Mini 2 and the Air 2S and I would love to use either Litchi or Dronelink for flight planning. Any idea when DJI is releasing their SDK with this functionality for these drones?

Based on a comment by the DJI developer on their git hub page it wont be coming - https://github.com/dji-sdk/Mobile-SDK-iOS/issues/456

Dear DAFlys,
Thanks for your message. Really disappointed. Do not understand DJI development team way of thinking. I am sure as more people are purchasing the Air 2S this item will explode.

I hope so,  but the SDK for the Air 2 is so bad that Litchi wont use it and until its more stable.

Would be nice if they added this!
