You have it orange-clouded so it will never resolve as a CNAME, it’ll resolve as two A and two AAAA records, with IPs pointing to Cloudflare’s proxies, and then Cloudflare’s proxies will do a lookup for that paperturn.com name you set and proxy the traffic there
If you want it to resolve as a CNAME you’ll need to grey cloud it and wait 5 minutes
Well, if I understand correctly, you’re validating with a third-party service “Paperturn”. So it depends whether they only validate that the CNAME is pointing to them once, or if they re-check periodically. You should ask them. You can leave it grey forever if you want, the traffic just won’t pass through Cloudflare’s proxy.
