I am using Spark 3.0.2 and latest Fastpath Webchat as clients for Openfire 5.0.5 with Fastpath plugin 4.6.0.
Whan starting a conversation in workgroup “my_workgroup“ from the webchat, “my_workgoup“ is shown in Spark as a partecipant in the conversation. Also, the sentence “changed the subject to “”“ appears in the chat.
It looks like an issue, since I did not notice this in earlier versions.
