Hi HarryB,
it happens to all images which we preload. On Prod we don't have these issues as we do not preload any pics dynamically based on viewport. Because of this, we have strong issues with LCP and CWV on Prod.
To improve LCP we changed on staging from 1 background image for all viewports to viewport based images with different size+ preload + fetchpriority. But this is getting overruled by webp rules from Ezoic.
We have 12k+ images to be excluded from next-gen format. Is there anyway I can give you a list of the filenames, and you bulk exclude them in webp?
All other images on our platform still need to be lazyloaded and transformed to webp so we cannot entirely switch off lazyload or webp.
Kindly let me know whether I can give you the list of 12k+ images (all already webp) and you could manually exclude them.
Thanks
Tom
