Troubles with lights, lumen and shadows on Vision Pro, how to fix it?

Hello,

I’m trying to export on apple vision pro for a project I have to do.

However I’m not able to use deffered shading, not able to have lumen and also now I have no shadow when I export to the vision pro.

Do someone know what should I do in order to fix this?
I’m using UE5.6.0

Thanks a lot for help!

Reducing the dynamic shadow distance in the light solved the shadow problem.

However the result is still very odd.
When Ï try to activate deffered rendering for mobile, the application crash on the vision pro..
