Custom Domain is not Available as Application Domain

Problem statement

This article will explain why a newly configured custom domain is not available as the application domain for new or existing applications.

Auth0 Dashboard > Branding > Custom Domains > domain:
Auth0 Dashboard > Applications > Applications> Select your application > Domain:


This is an expected behavior. Each application’s domain always points to the Auth0 canonical domain by default, even after configuring a custom domain.

Please refer to the following document:

to configure each application to use the new custom domain instead of the Auth0 canonical domain. The custom domain must be configured for each component separately.
