[Smush Pro] Solve “Properly size images” Google Page Quality Insight

Hi,

I’m currently using Smush CDN to ensure a better compression and image serving for enhance my Google Performance Test, but I still gets the “Properly size images” notification on opportunities.

There are images served by the CDN that apparently are not served at the correct size of the container.

Is there a mis configuration or something else that I should do to improve this?

Thanks.
