Reply To: AT Feature Section scaling on iPhone

Dear dphelps,
Such issues are common for the iOS devices as Safari browser still does not support background-attachment: fixed; property. But it should not appear
on the Android devices.
But you can add the following CSS code in Additional CSS for removing the blurry image from all mobile devices
Appearance > Customize > Additional CSS

@media(max-width:767px){
    .at-parallax {
       background-attachment: scroll !important;
   }
}

(Note: It will change in all mobile devices)

Best Regards!
