[WP Smush Pro] Smush CDN Beta making website way slower

Dear support team,

Following Predrag's request, I'm creating this ticket to notify you of an issue I'm facing with the smush CDN.

On my website : https://solutionsvisuelles.fr/
I granted support access.

Without the CDN, there is around 1 sec load time on Pingdom test: https://tools.pingdom.com/#5a04e29ab3800000

It goes up to around 15 sec when I activate the Smush CDN : https://tools.pingdom.com/#5a04dbbda1000000
