Facebook Messenger: no notification when offline on Android Steps to reproduce:


I go offline (turn off Wi-Fi, turn off 3G)
My friend sends me a message through Facebook Messenger.
I go online.


Expected result: I receive a notification about the message.

Actual result: There's no notification at all.

Extra info: If I'm online when my friend sends me a message, I do receive a notification.

So, how to receive a notification about messages sent when offline?
Update the app. If doesn't work, update the phone. If doesn't work, switch off and on your phone. If still doesn't work, uninstall and reinstall the app.
