title: Azure Notification hub wont send apple push notifications
body: <p>I was following this tutorial for setting up push notifications: <a href="https://docs.microsoft.com/en-us/azure/developer/mobile-apps/notification-hubs-backend-service-react-native#create-an-aspnet-core-web-api-backend-application" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/azure/developer/mobile-apps/notification-hubs-backend-service-react-native#create-an-aspnet-core-web-api-backend-application</a></p>
  <p>This was previously working and sending notifications to my phone through the notification controller. Since then it has stopped working. I can see that my device is registered in the notification hub and when I send a notification I get a 200 response from the server, so there are no exceptions happening. However the push notification is never sent to my phone. However, if I send a test notification from azure portal, the notification is sent to my phone immediately.</p>
  <p>Why would the notification fail to send when using the notificationHub.SendAppleNativeNotificationAsync, but successfully send when sending a test from Azure portal?</p>
