AUTHENTICATION_SERVICE_UNKNOWN_ERROR for some users

[UrielFrankel]

Hello,

We integrated the Spotify Authorization API in our app. Some users get AUTHENTICATION_SERVICE_UNKNOWN_ERROR when they try to log in.

After investigating this issue it seems that users that did not verified their Spotify  login email - will get this error. Can you guys check if you send back this error when the email is not verified? If so can you send a different error back to the API and simultaneously send a confirmation email that will solve this issue? Some of our users are in Limbo.

Thanks,
