Image Polish to Webp not working


I converted my website from the now Deprecated ‘Page Rules’ to ‘Cache Rules’.

When I tested my website before doing these changes, my images were being served with ‘Polish’ and converted to .webp savings up to 25 KB on images…

I saw this when I ran a speed test report:

I have checked the settings in my Cloudflare and they should still be serving .webp images, but they are not.

Is there any additional steps I need to take to get the images serving .webp again?

I have a Pro Plan in Cloudflare.

Thank you!
