We have a workflow that was developed through a developer/partner that was tested and worked.  Today, we pushed a candidate through the process and invited them to an in-office interview.  They were sent the booking link (as usual and as tested before successfully) and the candidate scheduled the interview for 2pm today.  The booking was scheduled and entered into the system and calendar.  However, the interviewer was not notified and I cannot figure out why and why, when we go to use the system after successful testing, is it not behaving!  Any help/guidance is greatly appreciated.
