I sent an email but I figured I'd also give the forum a shot in case others had seen the same problems. (And I managed to solve one already)
I'm syncing to an Android calendar. For one-time, ordinary meetings this works well. For recurring meetings that happen at regular intervals (every 3 days, every week, etc), this also works well. But for intervals landing on a particular day in a particular week of the month, the event is synced as though it happens every week. So for example, a meeting that occurs on the third thursday of every month instead gets synced as though it happens every thursday. Since I do in fact have a meeting on every third thursday, and every third friday, this causes a major nuisance on the phone, because the meetings show up every thursday and every friday.
Another blocking problem is the reminder sync. Sometimes my 15-minute reminders are synchronized correctly. But most of the time there's no reminder on the phone, or the reminder is set to a large negative integer, like -50823 minutes before the meeting starts.
Except for these two major problems, this software would mostly meet a need that I have.
