I'm trying to help a friend with his phone. It's a 4S running iOS 6.1.3. He uses a bunch of google calendars (his own plus a few others), and google calendar is configured to share entries between them. He's having trouble with his phone -- entries he creates in google calendar or on the phone don't show up in the other place. What can be done? He has already tried deleting all of the accounts and then adding them. I was think of deleting all the accounts and adding/debugging one at a time. Has anyone else faced this problem? Any advice to offer with how to debug this setup? Is there any reason why he needs to add multiple accounts to the phone if he already has sharing setup between the accounts?
