Calendar notification spam when nothing changed
I subscribe to notifications for a shared calendar between my wife and I. About once a week or so I'll get change notifications for nearly all events on that calendar. However, nothing has changed. In some cases, as today, there were 3 or 4 notifications for the same event. Again, nothing had changed.
This feature is more trouble than it's worth, so I have disabled it. Please do not send notifications if nothing about the event has changed.
