Universal Login preview not working?

When trying to edit our login page branding, the preview doesn’t seem to respond to any of the color/layout/sizing changes. The zoom, focus, and hover controls also do not seem to work.

I’ve verified:

  • The New Universal Login Experience is enabled
  • There’s no custom templates or html overrides being used for any page
  • I tried with multiple browsers and incognito mode.

It seems like it might be a problem with the Auth0 Dashboard, because none of the preview controls are working at all.
