I upgraded to 2.0.6 and since then, there are times when a group invitation chat comes through our jabber server instead of a group chat it shows up as an individual chat to my desktop. Also, I don’‘t receive a sound notification that a new invitation has arrived. This does not happen all the time but something happens so it doesn’'t come in as a group chat. It seems like when it happens once, it continues to happen until you logout of Spark and log back in.
I am going to have to roll back to 2.0.5, and will inform my users not to upgrade to 2.0.6 until we have determined what the issue is. If I can provide you any additional information please let me know.
