CP won't let me reschedule a 12pm - 12:45pm meeting to 11:30am because the meeting type has a 30 minute buffer before it. The solution would be for CP to keep track of meetings it had booked and know that meeting ID XYZ from 12-1pm is the same meeting ID XYZ that is attempting to reschedule and therefore, treat the buffers and the meeting as free. Today's workaround requires me to delete the buffers AND mark the meeting as free in Google Calendar. Not a great workaround when the attendee or my assistant is trying to reschedule for me.
