I am new to Sales Starter (came over from Calendly when I upgraded my HubSpot account) and I am shocked that when I did a test by creating a Meeting and then, after the person accepted the Google Calendar invite, cancelled it...and the person did not receive a notification that the meeting was cancelled. This seems so basic. Why is this not a feature already? With Calendly, both I and the attendee would receive a cancellation notification (along with the reason if I added one). This needs to be added.
