Ahh, I wasn’t aware the test Auth0 Email Provider was being used in your tenant, sorry!
This FAQ post confirms that you must setup your own email provider before using any customized email templates: Why is my passwordless email template not working?
As far as the misspelling for the default email template in the meantime, try checking in these two places
- The spelling of the application name under the
Auth0 Dashboard > Applications
dashboard - The spelling of “Friendly Name” tenant setting under
Auth0 Dashboard > Settings > General
