title: Push Notification to multiple devices at once
body: <p>I am looking for some input on what might be a solution to the case where I will have to send a push notification to many devices at once.  The notification will retain the same message for every device that it is sent to.  I have looked into AWS SNS, but I was unable to find anything on the idea of subscribing multiple devices to one topic, or if this is a possibility?  If not, another solution to this problem would be to loop through n device tokens which might not be the most efficient way of doing so.  </p>
  
  <p>If you have any other recommendations, they would be greatly appreciated!</p>
  
  <p>Thanks in advance.  </p>
