Using apns to update wallet passes

Hey have a few questions regarding updating apple wallet passes using APNS.

  • What happens if the receiving device is switched off? Is the notification sent again by apple or do I need to send again myself?
  • On booting the phone are passes automatically updated? e.g. Do they make the request to my server for a new design - or will the user need to force refresh / send the apns notification again.
  • Does low power mode affect any of the pass update flow?

Thanks!
