title: iOS Push Notification When app is killed
body: <p>I was wondering how does WhatsApp handle the Video Push Notification when the app is killed from the background. Taking into consideration that the app icon is clicked and not the notification.</p>
  
  <p>1- The Push Notification keeps showing every 5 seconds</p>
  
  <p>2- The Ringtone plays single time although the app keeps showing push notifications for around 30 seconds.</p>
