Pageonce 3.0 Calendar Sync issue

This is a great upgrade , however has anyone been able to get the calendar to sync when you get new notifications? I have sent the company 3 emails with not much luck. Seems like a great feature, but "does it really work"? Thanks for any answers and or help.

It didn't work for me at first, but I just received my first calendar notification from it yesterday. I'm not sure how it works...maybe it doesnt appear until a certain number of days prior to due date?
