Push service: subscription to push.rx.notification() continually emits same notification

In the Ionic Push docs it states to use a similar snippet of code to this, which I have implemented in our mobile app:

  .subscribe((msg) => {
    alert(msg.title + ': ' + msg.text);

The only difference being that instead of alert I am using the Ionic toast to present it.

When a push notification is then pushed to the device running this code, it seems to infinitely present one toast after another. Anyone had this happen? Any thoughts why?

The unsubscribe method is used when the application no longer wants to receive push notifications from a specific topic but continue to receive other push messages.
