Cloudflare Cache Everything and CSRF token mismatch

Hello!

We are trying to use the CF option Cache Everything for an ecommerce website.

we are getting CSRF token mismatch for all ajax requests. How should we go arround this? After reading this article (Ecommerce websites on Cloudflare: best practices) it seems possible to set up the dynamic portions of an ecommerce website with ajax and serve the rest from cache.
