1) Does not allowed to save location preference for future use; when making appt.,must keep searching for desired location 2) Does not remember login on next use;each use of app must log on 3) Cannot cancel or reschedule appointments 4) Does not send reminder notification when set up to notify 5) Would be nice if these features are added,I think it would clear unwanted appointments for others to take,save time on login each time & searching for location
