The Dynamics customer self-service portal allows you to configure a custom domain, for example: www.mydomain.com
But the "www" is seen by DNS as a CNAME.
Nowadays it is normal to use only https://mydomain.com for website and it is exactly at this moment that the Dynamics portal does not allow configuration.
I tried several third-party DNS, including Cloudflare, I also tried Microsoft 365 DNS but I was unable to configure it using only the root: http://Mydomain.com.
Please consider allowing the dynamics portal in powerpages to be configured with custom domain root as well.
