Can you give more info on how the phone updates track info. Is there anything that would block this info on our routers. Is there anything on the phone needing permissions etc. Thanks.
The old status page would show active event subscriptions on each player, but that was removed along with many other useful features a few years ago.
Updates are done via a UPnP event on the AVTransport interface of each player: the player sends the event to everyone who subscribes to it. If the app doesn’t respond to an event 3? times the player will stop sending the event.
In the general case, firewalls will block this eg on a Windows WiFi network in “public” mode as it looks like an unrequested call from player to app. VPNs also have a habit of blocking event callbacks.
