Our Free tenant continues to render a previously configured Universal Login page template. The normal hosted login widget and supported English/Simplified Chinese text settings work, but the old custom surrounding copy remains in English.
GET /api/v2/branding/templates/universal-login returns HTTP402 with “A paid subscription is required for this feature.” Authentication and other permitted Management API reads still work, so this is a feature limitation rather than a login failure.
What is the supported free way to remove the retained custom shell and return to the standard New Universal Login page? Can Auth0 staff perform that reset without a paid upgrade? We want to retain the existing custom domain, clients, connections, consent Forms/Actions and users, and do not want to switch to Classic Login or bypass plan restrictions.
