Auth0 universal-login customize Deploy Changes not working

Ready to post? :mag: First, try searching for your answer.
I’m trying to use the auth0 universal-login customize command to change the look of the login page.

I can run auth0 universal-login customize, make changes and see them in the preview panel but click “Deploy changes” doesn’t cause any changes to the login page.

I don’t know if or where these changes would appear in the Auth0 dashboard and I’m seeing mixed comments about when Customize Login Page should be enabled or not (This is the toggle in Branding > Universal Login > Advanced Options > Login).

Can anyone point me in the right direction? I cant see anything in the docs that suggest other steps are needed.

Eventually found this: Universal Login Page Template not working for me - #10 by blake.symonds

The issue was that I had a custom domain enabled but I was accessing the UI through Auth0’s domain.

As soon as I started using the custom domain, the template was loading as you’d expect.
