Unable to decommission Azure Front Door - DNS related problem

When I am trying to delete a CDN from the Azure Portal, I get this error message:

Cannot delete custom domain "shop.cafebox.com" because it is still directly or indirectly (using "cdnverify" prefix) CNAMEd to CDN endpoint "bigcitycafewebcontainer.azureedge.net". Please remove the DNS CNAME record and try again.

How can I delete it successfully?

    Hello EnterpriseArchitect

    If the DNS records are already removed but Azure still blocks deletion, you can try registering a feature flag:

    az feature register --namespace Microsoft.Cdn --name BypassCnameCheckForCustomDomainDeletion

    Make sure you're using Microsoft.Cdn (not Microsoft.Network) as the namespace.

    After registering, wait for the feature to be enabled (you can check with az feature show) and then retry the deletion.

    I hope this has been helpful!
