When a contact has information like email and job title filled, Spark will show this information near the avatar, when you open a chat window with that contact. It also shows same fields in the short and full profile of a contact. But there is a time interval by which Spark will check for vCard updates (60 minutes probably). So when a contact changes something, it is not reflected until Spark refreshes this information or a user pushes Refresh button manually. We should investigate why this time interval is in place and maybe make Spark checking profile instantly when opening a chat window or profile window. Unless it is done to protect a client or server from vCard request overload. Then this ticket should be closed as Not a bug.
