Is it possible to share a Google Calendar subscription with multiple iCloud users? My sister has given me complete shared access to her Google Calendar so I can publish it to my iCloud calendar and share that with all the iOS users in the family.
Initially I simply exported the calendar file and imported it in OS X's Calendar App, then shared the new iCloud calendar. I have been notified that this calendar will now be updated on a regular basis.
I have been unable to locate any type of sync settings or app that would keep these two calendars in sync. Any suggestions?
