Does the LitchiApp support the DJI Zenmuse Z30 camera?

We use a DJI M600Pro with A3 PRO flightcontroller, Lightbridge 2 and a Zenmuse Z30 camera.

I am able to control nearly all functions of the Z30 and the gimbal, but the zoom-function doesn`t work!

I`ve also tried to hold donwn C2 button and use the left wheel, but there is no reaction!

(This combination works on the DJIGO-App without any problems!)

I´m also able to adjust the EV with the right wheel, so there have to be a connection to the camera.

Does anybody have an idea what could be the problem with the zoom-function?
