About this task
Note:
There is no way for the instance to guarantee or confirm push message
delivery. For more information on how Apple handles push notifications, see the
Local and Remote Notification Programming
Guide for Apple developers.
Messages can also fail to send for several reasons, such as a large message queue or other issue with the instance. You can use a system property to control how long the instance queues a push notification after it is triggered.
Push notification message payload size is limited by provider:
- Apple iOS: 2,048 bytes
- Google: 4,096 bytes
