Interviews cancelled in VSys One versions prior to 2.1 don't generate the "transitions
" records needed for this event to work; the interview must be cancelled by version 2.1 or later.
If you just make a new interview record with a status of Cancelled by interviewee, VSys won't detect that as a "Self-cancelled interview". Why? VSys doesn't look at the current status of the interview when it's first searching for records to use here, instead it looks for records which once had some status other Cancelled by interviewee but now have one that is Cancelled by interviewee. (That also means that an interview whose status was changed by an older version of VSys One won't qualify here, either.)
VSys doesn't know that the volunteer herself did the cancellation, instead it detects that the interview's status was changed to Cancelled by interviewee within the Cancelled between window.
One notification is generated for each interview meeting your criteria here, each with the interviewee's name and information about the interview.
