If I login from two XMPP clients at same time (eg. Pidgin, Jappix, Xabber or Chatsecure on Androïd), the chat messages are delivered only on one client. Why the messages do not get delivered on all the clients I am logged-in to?
That’s a known issue of the XMPP protocol.
This is actually the default behavior of XMPP, if you want to modify this and try out new ways to receive messages, you can activate the message_carbon plug-in manually in your Metronome’s configuration.
@kload I will try the message_carbon plug-in and update the post.
