I’m using siteground fo hosting and I set up cloudflare for the following website (subdomain is active on siteground portal) : https://www.preprod.stmauto.fr/
Performance on google insight are good however, website is working only on desktop. There is an issue on mobile phone (home page is blocked -> style issue ??).
I have entered the following url on autoptimize plugin : https://prnt.sc/twsoty. If I remove url in autoptimize plugin, everything works but performance are very bad for mobile device.
Thanks for your help
