when I turn spark client off and on again (or upon a /scheduled/ reboot) with unread messages, I am no more notified, so I lose the track of them…
tested with 2.8.3 and 2.9.0
Spark doesn’t have a feature to keep track of unread messages. Even when simply closing chat window.
I have filed this as a request https://issues.igniterealtime.org/browse/SPARK-2060
But as Spark has not active developers, i doubt it will be implemented anytime soon.
