I'm working on a new product and would like to use FD as well. We do not want our customers directly adding CNAMES to our FD instance, but that is the only option. If we ever need to migrate to another service or FD instance, each customer would have to update the records.
Please allow FD to validate by following a CNAME record so we can do: app.mycustomerdomain.com -> cloud.myapp.com -> myapp.azurefd.net
Thanks for the valid suggestion. Your feedback is now open for the user community to upvote which allows us to effectively prioritize your request against our existing feature list and also gives us insight into the potential impact of implementing the suggested feature
