First, let me state that the calendar feature is terrific when it works. I get notifications at reasonable times (a day before and then leading up to the departure time). However, I can't rely on a calendar entry being recognized by Waze in a timely fashion. I have no idea what the cycle time is for it to check my calendar and then add it to the app. Furthermore, I think the problem is exacerbated when I make an event change (move the meeting to another day) vs. creating a new event altogether.
Any thoughts?
