Site very slow on iOS16

There seems to be something really wrong with our webflow site on ios16. The pages with collections load very slow and everything is very jerky (eg. Scroll effects and animations). On iOS15 everything works as except. I have now tested on newer phones and older ones and all with iOS16 installed have these issues. It does not matter what the browser is (Safari, Edge, Chrome, Firefox, etc.)

This is a really big issue for us as we are launching 3 sites in multiple languages all with CMS heavy content. I would be happy to give you more information over teams or any way that helps tracking the issue.

The sites affected with these issues are the following:
