[WP Smush Pro] Problems with image smushing and CDN

Hi.
Hummingbird is showing a slow performance on the images. I have activated the CDN and I have Smushed images. After everytime i Smush (and cleared cache) I recheck the performance in Hummingbird and get the same 23 images needing Compressing and some need resizing.
Google Speed Insights are confirming the same. Shouldn't this be handled using the CDN?
Or am I missing something?
I have granted access.

Regards,
Ralph
