User subscribes and unsubscribes (by mistake maybe). If he wants to subscribe again, with same email, API says 'Success', but his email is added to suppression list. After removal of that email from suppression list, user tries to subscribe again, API says 'Success' but this time email is not in ether list. Is this bug or i missed point?
Hi minus. In order to add that person back to the list you'd need to use Subscriber.AddAndResubscribe rather than just Add.
