Cloudflare blocking Klaviyo user agent - Help with IP Rules
Cloudflare is blocking the Klaviyo user agent for some reason, and we can't update and sync our product catalogue. This is the log from Klaviyo:

Could you please check with Cloudflare to understand why this request was blocked despite the whitelist rule for this IP address being in place? Let me know what you find, and we’ll continue to assist from there.
I have a rule that includes all of Klaviyos IP's and they are set to SKIP, but for some reason Cloudflare still blocks them. Can you help?
