Hi, this is a bug report,
When using universal login without a universal login template, the background image works.
However, when a custom template is set, the background image stops working.
Note by custom template, I do not mean the login page template override, I mean the universal login template, as per “Customize Universal Login Page Templates” in the Auth0 docs.
The style for the background image is set against a class, but that class is not present on any element in the DOM, which means it won’t be applied.
We are exploring a work around where we set the background image style manually, however this is not ideal as it means the WYSIWYG editor is not being respected.
