We are trying to use the .NET WPF library for Auth0 (version 3.1.7) on .NET 4.7.2.
When attempting to authenticate with Passwordless, the login button is greyed out in the login browser window, even when a valid email has been entered. The Passwordless (email) connection is turned on as is the Passwordless (OTP) grant type in the app settings.
If the “email” connection is explicitly specified, the login window doesn’t even appear. The request fails with access_denied.
