Hi @Nicolas-Flam we now support webp images feel free to upload them on your website and your pagespeed grade should increase !

@oren-benitah hi, your issue is related to your cookie consent code that overrides the window.onload function.

You can fix it by adding changing your code from this:

window.onload = function() {
    cookieConsent();
};

To this:

window.onload = function() {
    window.setupCheckout && window.setupCheckout();
    cookieConsent();
};
