I am using GP Pro and GB Pro on this new site. When I run Pagespeed or Webpagetest, I see reports indicating that on mobile, the tests are serving smaller-sized images than on for desktop. Is GP, GB or WordPress core now controlling this? I do have AVIF enabled through Shortpixel, not sure if this contributes to this behaviour. Any thoughts?
Thank you. Given that WordPress does control this, I guess there is finally a use for the smaller media sets! By the way, when did this start happening? I was not aware of this and always thought you had to rely on a CDN to serve varying sizes. Thanks!
