Best iPhone/Mac calendar integration?

I’ve found the iCal link on the Manage->Settings->Edit Troop Settings->Calendar Integration, however, that seems to do a static download of the calendar items, and further calendar updates are not reflected (even if the calendar is “refreshed”). Re-clicking on the link updates the items.

Is there a way to get a dynamic calendar link on the iPhone/Mac?

Thanks

Ugh, even worse, it doesn’t delete calendar items that have been removed or rescheduled… This is very problematic!

OK, so what IS the SUPPORTED dynamic calendar solution then??
