So got the FPV Drone and got everything avtivated and updated then right at the end swithced the mode to the FPV mode to try it on a air unit and everything was working great. Went out to fly snd swithed back to the Drone FPV mode and "lost video transmission signal" or somehting along those lines, in a red warning in the goggles. Turned it offf and on quite afew times and nothing, tried refrrshing the firmware and it fails every singl time, tried connecting to the Fly app and nothing.

Any ideas?

I have the same problem. when switching from DJI FPV to FPV mode, I have to re-bind over and over again

I thought you meant you are rebinding your Air Unit, so I didn't do anything then I saw another reply saying to rebind the DJI Drone and i cant believe it was such a simple thing.
Thanks mate.
