Hey there,
I ran into the same problem with Divi. I have a Background Image and I do not get the .webp-Version of it. (500KB vs 80KB).
I do not care that much about lazy loading, but webp-Delivery would be great. I tried the Beta and it is still png – just for Info.
Guess this is the problem:
div.et_pb_section.et_pb_section_0 {
background-size: initial;
background-position: top center;
background-image: url(https://XXX/XXX.png),radial-gradient(circle at center,#ffffff 65%,#ffa7c1 100%)!important;
}
Thank you for your great tool Frank!
Greetings
Andy
