Dialogues in the general chat are not ordered chronologically. The top positions in Wazzup are always given to the clients who have not received an answer from you. Such approach to sorting prevents you from missing such dialogues in the overall communication flow.
In Wazzup, there are no “unread” messages; what matters is whether a message has been answered or not.
To make a notification about an “unanswered” message disappear, you need to reply to a client or press the “No reply needed” button. Not a single dialogue with a client that has not been replied to can disappear from the dialogue list by mistake.
If a dialogue does not have any unanswered messages left, the icon will be changed to a green arrow.
