How do I get my shared Google Calendars to show up?
You need to tell Google to sync all your sub-calendars to your iPhone: you can do that here:
Exchange / Second option
If that doesn't work, please try the following:
- From your iPhone browser, go to https://www.google.com/calendar/syncselect
- Sign in with your account and you will be able to select calendars you want to sync with your iPhone.
- Please ensure that the language of Google's site is set to English for your iPhone
- Go back to the calendar application and you will have all your calendars you have selected.
