No email notification is sent to meeting organizer when it is responded to

Information: If you respond to a meeting
invitation on your device (accept/tentatively accept/decline), the
meeting organizer will not receive a email notification that you
responded. However, their calendar will be updated to reflect your
status. This is consistent with the native behavior of Google Calendar.
