Hello, Aasem,
Thank you for the response.
It could be caused by this option -> https://prnt.sc/s9ABxKGWl9zq . Please, try to set it to normal and check then. According to the next web-site (where it is possible to check different CSS properties) -> https://caniuse.com/?search=mix-blend-mode it seems that such CSS property could not work normally in IOS mobile -> https://prnt.sc/UTp7OGEhzh9O
Also, we have added the next custom CSS to your child-theme/style.css
.etheme-elementor-slides .swiper-slide .etheme-background-overlay {
transform: translate3d(0,0,0);
}
so, could you please, check now, we tested it and didn’t find any issues.
Kind Regards,
8theme team
