 The zone named <ASE name>.appserviceenvironment.net is globally unique. Before May 2019, customers were able to specify the domain suffix of the ILB ASE. If you wanted to use *.contoso.com* for the domain suffix, you were able do so and that would include the scm site. There were challenges with that model including; managing the default SSL certificate, lack of single sign-on with the scm site, and the requirement to use a wildcard certificate. The ILB ASE default certificate upgrade process was also disruptive and caused application restarts. To solve these problems, the ILB ASE behavior was changed to use a domain suffix based on the name of the ASE and with a Microsoft owned suffix. The change to the ILB ASE behavior only affects ILB ASEs made after May 2019. Pre-existing ILB ASEs must still manage the default certificate of the ASE and their DNS configuration.
