Tether caption Nikon Z9

Hi all . Need your help .

Trying to cable tether nikon Z9 & Z8 with Lr but the camera does not write images on the card.

Everything is up to date (cameras and Lr14).

Also the moment i tether the cameras the format card menu in the camera goes grey..

I tried everything . Luckily i was able to use Nx studio for the job.

But the Lr suits my needs way better. 

Any solutions , ideas ?

Thank you in advance all !!!
