It has come to our attention that there is an issue with the Communicator Integration feature.
This happens in the middle of uploading the email addresses. Sometimes the progress will show 25, 50, 75 or even several hundred, but at some point, this error may occur. The cause of the issue is being investigated and we are working hard to get to the bottom of this as soon as possible.
The puzzling factor here is that nothing has changed in the CMS application that would cause this. Initial review indicates that something in the process outside of CMS is causing a disconnect or interruption in the communication from ChabadOne.
