I am a Spark 2.9.4 user and I think I ran into a refresh bug in a chat room.
When I chat in a room my message is not displayed in the chat window but the user can see my message. if I close the living room window and relaunch it, my message is indeed present in the history.
I wanted to give you a ticket in the tracker but unfortunately not the rights to do it
Thank you and see you soon
