I keep getting errors in pagespeed that my images can be reduced by up to 80%. I have emptied the ewwwio table and bulk optimized everything with the "Force re-optimize for Media Library" checked.
The bulk optimization passes the images in question but the only remark is no savings. Manually downloading the images and optimizing them works and actually reduces the filesize by the amount mentioned in pagespeed. Plugin displays no error and all files show as a green OK.
As all images in question are custom sizes added by the Theme (Avada) I guess the plugin cannot deal with this.
regards and thanks for your work!
