After updating plugins in wordpress, cloudfare cache doesnt work anymore

I have updated several plugin on my website, after updating I can see the cloudfare cache is not working anymore. the percentage cache is moved to almost 0%, before it was 70/80% about.
What could cause this? Do you have a sort of checklist to understand if something is blocking the cache? thank you

Sometimes it just takes a while for the Cloudflare cache to refresh. But if you provide your domain name, we can take a look to see if anything is still set for caching.
