We have a use case like User-A can see the list of channels where he is part of the group channel.
User-A has opened the group channel chat and had some conversation with User-B and then he closes the chat window. After some time User-B has sent some couple of new messages. Since User-A has close the chat window for him the new messages should be shown as unread message, But all the new message are getting consider as read & User-A is missing the those messages.
So to fix the above issue please let us know how to close the group channel season properly. We are using “sendbirdmin.js” & “chat.js” like websample app.
