Hi All,
Apple's documentation states:
Apple Push Notification service includes a Quality of Service (QoS) component that performs a store-and-forward function. If APNs attempts to deliver a notification and the destination device is offline, APNs stores the notification for a limited period of time and delivers it when the device becomes available again.
Do anyone happen to know the details of what that "limited period of time" is? My team is trying to document some things and it would help to understand this. How long do users have before any queued notifications expire in Apple's system?
