3D FlipBook - Blank on iPhone 16 Pro running iOS 18.1

Loving your jQuery plugin, but I'm having issues getting a FlipBook (https://theartisan.williamsandtaylor.com.au) to load on my mobile (iPhone 16 Pro, iOS 18.1).

It's blank on Safari and doesn't seem to report in any errors, yet it loads fine on my browsers (Safari, Firefox, Chrome), on my phone (Firefox, Chrome) as well as on other people's phones, including older iPhones.

Thoughts?
