Custom domain mapping issue: App resolving to default .run.app URL instead of custom domain

Description of the issue:

I am trying to map a custom domain to my deployed application, but the URL is reverting to the default Google Cloud Run service URL.

​Expected behavior:

When navigating to my custom domain (iconic-sevens.ai.studio), the application should load directly on that domain while keeping the URL in the address bar intact.

​Actual behavior:

When configuring the publishing URL as iconic-sevens.ai.studio, the application instead resolves to/displays the default Cloud Run URL:

Iconic-se7ens-ic7-844393628389.europe-west2.run.app
