My team has a development tenant that we set up with an Essentials subscription and a custom domain several months ago. We also enabled the custom domain for email sending.
Recently, we decided to downgrade the dev tenant to the Free tier and stop using the custom domain. However, it seems as though the setting to send emails with a custom domain did not reset when the downgrade occurred. This results in password reset emails being sent with the custom domain in the reset URL, despite the fact the domain no longer exists.
Because we are now Free tier, we have no way to disable this setting ourselves. How can we reset our account so that email URLs contain the default Auth0 URL again?
