I'm building a thing where that will be hosting customer websites using cloudflare pages. For example, my website is kelly.com and using cloudflare pages the URL for a customer's pages website might be customer.pages.dev.
To set up a custom domain, a customer might set up a CNAME from example.customer.com to customer.pages.dev. This is ok although I don't want customers to need to use customer.pages.dev, I'd rather they have customer.kelly.com.
My current plan to resolve this is to add a custom domain to the pages project, customer.kelly.com, and tell the customer to use customer.kelly.com, so it would be example.customer.com -> customer.kelly.com -> customer.pages.dev.
Is there any issue with this approach? I want to try it out and am getting CNAME Cross-User BannedCNAME Cross-User Banned when I load the domain the customer uses.
