We would like to use App Service Managed Certs for our webapps, but they reside behind Cloudflare. Because of this, ASMC will not validate because the CNAME doesn't point to azurewebsites.net. Is there any plan to add alternative validation methods? Checking if the custom domain in the web app is already validated is used to validate paid App Service Certificate purchases now. ASMC should be able to do this as well I would think.
