So now when the sdk is released, any news when will litchi add support for mini 3 pro ?

Hi there. Thanks for reaching out. We're sorry, but we have not received such updates as of writing. Only SDK is currently supported. We will continue to communicate this request to the DJI Developers for consideration. We appreciate your understanding and support. Have a nice day!

You should ask Litchi on their forum,  they have the SDK so its down to them,  the bad news is the new SDK is not compatible with the previous version so its a big rewrite for them.  And they will probably have to have two versions of the app going forward.
