Raw Image wont render on update

I'm using AVPro to Play a video which being assigned to a material in RT which works fine.
However, I want to play this video on a rawImage as a UI window and that raw image only renders the 1st frame and nothing past it.

there is no point in using rendertextures as AVpro has its own video material


Which all in all works fine except for the issue of the Raw Image not rendering it.
Should I force refresh the image every frame?
Or is there a solution?

 

thank you, I wonderedw which forum should it fit.
reposted it there.
