We’re using Elementor with WP Rocket and Imagify https://imagify.io/
Imagify is creating WebP versions of images and serving them fine on most images across the site.
But I have noticed when doing a Google Core Vitals test, the background images are not using the WebP files. This happens in when using the banner slider.
See the attached for the settings in Imagify, which is using ‘Use <picture> tags’
Any suggestions for to fix this, so WebP images are used in background elements?
