title: Azure Notification Hub's Expiration Date
body: <p>When I view my <strong>Azure Notification Hub</strong>'s device registry, it has a column called <strong>Expiration Date</strong>. My question is, what happens to the registry after the expiration date? Do clients get notified that their notification hub registry will expire and will need to register with GCM and notification hub again in order to receive future notifications?</p>
