Who can I contact for an update, that I can't use the Crystalsky as a screen for the camera... And I don't understand why if I connect microhdmi-hdmi I can't see my Sony projected...

Don't waste your time.. DJI is not interested in helping or supporting their products after they already have your money... expect a commie approved message "Oh Sorry, we'll pass on your request to your engineers" or "This feature is not supported at this time" because the HDMI connection is there only for decoration and as a marketting ploy...
