Iphone Max/plus Phones Not Displaying Cart Page Properly

Hi Everyone,

Got a strange problem on my Wix Store - Iphone Pro Max / Plus users are getting a different cart page than other users - the layout will not change to the mobile layout and is instead attempting to squish the normal cart page onto the phone display, images attached.

Pro Max / Plus display

Does anyone know how to fix this issue?

Thanks in advance.

Jake
