Push notifications are not meant to tell if a client has dropped offline, they are meant to bring that client back online! What's not really cool is that as it is currently implemented in servers (and that can hardly be changed), push notifications are sent on every received message that is put into an archive, to all registered devices. SO, even if you're temporarily online, you do get a message and a push notification. But that's a minor issue. Also, curiously, there is evidence that FCM notifications are themselves implemented via a modified XMPP. -- Andrew Nenakhov CEO, Redsolution, Inc. https://redsolution.com _______________________________________________ Standards mailing list Info: https://mail.jabber.org/mailman/listinfo/standards Unsubscribe: [email protected] _______________________________________________
