I think scrolling all the way init, and graying out the previous chats from older sessions maybe a quick workaround for the moment.
@stuartH
the undefined issue was fixed
The other thing I'd like to see is a responsive chat box
Please add ability that group members can chat together, for example all of @administrators can chat together (or some thing better instead of adding users manually in chatbox we add hole group members )
@sanatisharif for this feature.
+1 for the feature
+1 me too
