The current Google calendar sync works as a pull from a Google calendar into a Blackbaud K12 product calendar.  This limits viewing the complete calendar to onCampus as some events are created there, and others may have been created in Google. Only the events created in google will show up when viewing the calendar google or a feed from google on a phone. As many people have the schools google calendar configured on their phone it is the preferred method of checking their calendar and the method they know.
