As of right now, the only way to see, through the calendar, that a grouped appoinemt has a canceled spot inside it, is by clicking on the actual apointment and seeing through the popup on the right.
That’s a huge issue, since its not practical to do that if you have hundrets of appointments every month.
PLEASE add the ability to display an appointment like that as NOT GROUPED in the calendar.
