Missing Mesh on Iphone

Hi! I’m having some issues with my model on mobile. So far it’s only been on Iphones that I’ve encountered this issue however.
When loading my model on mobile, some parts of it, in this case the head, are completely missing.

I have noticed that the mesh reappears when switching to Wireframe mode

And the mesh will also appear and stay until the site is refreshed if you turn post-processing off and on again.

I’m not sure if this is an issue with my model or the viewer on mobile. This doesn’t seem to affect desktop, only mobile. The model can be found here;

Hi @Crazicide - here is what I see on a Pixel 6a/Chrome and an iPhone 13/ chrome + safari.

Can you share some information about your phone / browser setup?
