I’m just making wild guesses here … maybe the DA dashboard doesn’t support custom domains yet? It is not explicitly mentioned in the list of features that support custom domains, though it may be implicitly included in one of the other listed features.
You guys are correct. The backing code is actually there, but there needs to be a way to enable it officially. @markd you should create a ticket and send me the email for it and I’ll forward to the right team.
This item is on the backlog, but currently doesn’t have a delivery date. In the long run, we will likely replace the Delegated Administration Extension with a core feature, so I’m not sure if this will happen before that date or not.
@skjolber Sorry for your frustrations. Unfortunately getting custom domains working with the Delegated Administration Extension is in the backlog, but not targeted for a particular release date yet.
Great news! The Delegated Administration Extension now supports Auth0 custom domains. The extension is live, and you should be able to use the new feature now.
