Push feedback

Feedback refers to the information about failed message delivery and the push applications that can no longer receive push notifications.

The instance uses a scheduled job to pull feedback data every hour from the APNs. When the APNs determines that a device can no longer receive push messages, the corresponding device in the Push Installation [sys_push_installation] table is set to inactive, thereby making it unable to receive push notification messages. If the same device is again able to receive push notifications, the device receives the same token and a new record is inserted into the Push Notification Installation [sys_push_notif_app_install] table.
