Question:
Why is a warning regarding Attendee Calls not shown to users when Rescheduling or Modifying a Unique Activities Call from My Schedule?
Answer:
Rescheduling and Modifying Unique Group Calls from the Call Page displays the following warning whether or not the Parent and Child DateTimes are synced: Update Datetime of Attendee Calls?
This warning does not display when rescheduling from My Schedule - but the Child Call DateTimes are synced to the Parent DateTime.
