New Customer Account Page Broken after adding custom domain

[PeterX]

I have added my own domain to my Shopify store, and I have added a subdomain for the new customer accounts (account.guardslondon.com). The CNAME entries in the DNS have been set up with my domain registrar as instructed, however I am still receiving an error page. In my Shopify admin I get a "Needs Attention" notice, however this is signaling that my domain is connected to Cloudflare which is not the case. Both the top level domain and the sub-domain for the accounts were added at around the same time. The top-level domain also has the Cloudflare warning but is displaying with no issues (guardslondon.com).

In case anyone else has the same issue, I resolved this by deleting the domain from the Shopify Domains section and then adding it back again (make sure to do this through the customer account section and not directly in the domain section or you'll just add the page back as a redirect to the homepage).
