This also assumes you've enabled all the system actions in CB Auto Actions for replacing GJs notifications with CB Activity notifications. If not please be sure to enable them. Note those auto actions replace GJs notifications. If GJ notifications are not enabled in GJs settings then it won't have anything to replace for example.
