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 actions to retrieve the messages that were received while your application was not active.

Note that lost messages system is not a guaranteed to capture all messages while the App is in the background or closed. None of the operating systems, guarantees their delivery or that it will always deliver them to the App if the App is in the Background or closed.

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.

On iOS the target "From" is not available.

Be aware of limitations imposed by Apple/Microsoft/Google on messages sent to background Apps. See this notice from Apple documentation for example: The system treats background notifications as low-priority: you can use them to refresh your app’s content, but the system doesn’t guarantee their delivery. In addition, the system may throttle the delivery of background notifications if the total number becomes excessive. The number of background notifications allowed by the system depends on current conditions, but don’t try to send more than two or three per hour.
