[QUERY] Missing notifications on ios 13+ with apns

**Query/Question**
I have a notification hub which is able to deliver notifications for old iOS versions. I began updating gaps introduced by later releases of ios, but I can't get it to work.

My code is quite basic:
```java
public class App {

public static void main(String[] args) throws Exception {
String hubId = "...";
NotificationHub hub = new NotificationHub(
"Endpoint=sb://...",
hubId);

Map headers = new HashMap<>();
headers.put("apns-push-type", "alert");
headers.put("apns-priority", "10");

String src = "{'aps': {'title': 'Alert notification', 'body': '" + LocalDateTime.now() + ", have (" + new Random().nextInt(10) + ") alerts'}}";
String body = src.replaceAll("\'", "\"");

Notification notification = Notification.createAppleNotification(body, headers);
NotificationOutcome outcome = hub.sendNotification(notification, new HashSet<>(Arrays.asList("_valid_azure_device_tag_")));
System.out.println(outcome.getNotificationId() + " " + outcome.getTrackingId());

if (outcome.getNotificationId() != null) {
NotificationTelemetry telemetry = hub.getNotificationTelemetry(outcome.getNotificationId());
System.out.println(telemetry);
}
}

}
```

***Why is this not a Bug or a feature Request?***
I am not quite sure if above method is supported given #48 is closed. I do get a tracking id but no notification id. Repeating same operation via azure console returns "Successfully sent test message. Outcome: {0 passed, 0 failed}. Please see result section for details."

**Setup (please complete the following information if applicable):**
- `Notification-Hubs-java-sdk` v 1.1.0
- `Java` 11
