Ambient Occlusion only renders on half screen? 2.4 / IOS / Newb

THE PLATFORM: iPad
NOMAD APP VERSION: 2.4

First time user, just setting up app preferences and see ambient occlusion only renters on the left-hand half of the screen (in landscape and portrait mode. )I’ve restarted and played with Settings all to no avail. Am I Missing something obvious or has anyone else had the same experience / or found a workaround? Admittedly, it’s a low spec iPad but It can handle global illumination, subsurface, etc. no problem so I’m wondering if it’s a bug ?

any help Much appreciated.

cheers

What’s the iPad model?

Thanks Stephomi - sorry I missed this.

Testing out on an old 7th gen. Appreciate you
