- If a message is received and your application is not running, the O.S. will make the appropriate display of the message, and if you enabled the "Save messages when application is not active" option in your project properties, it will be saved locally on the device. You can use "Push Notification ... Lost ..." actions to retrieve the messages that where received while your application was not active.
- Lost Messages are also saved if the event Push Notification Received is not executed for a specific message. (Application is closed or application is open but the event is not handled neither by the current nor the first form)
- Lost messages are mainly for data messages. Notification messages will normally not be captured. (On Android if application is open, they may be captured, because there is no way to tell them apart). If you want to handle lost messages, but also send a user notification, send 2 messages, one data message that will be saved if the app is closed, and one notification message so the user can be notified.
