The Enterprise Login button appears when using the “Try” Button in the Auth0 Dashboard and via all other Apps. It does not appear only via this one real application. However the missing enterprise connection is activated for the application.
As far as I know, we never needed to add specific connection parameters to make Universal Login show Enterprise Login buttons and was not able to find something in the documentation, e.g. New Universal Login Experience
Are there any API params or anything that we have to pass to make the buttons appear?
