I have an iPad and wife has iPhone. We are using one iCloud account to share contacts, calendar, reminders, etc... And then separate sub accounts on iCloud for email only. The problem is under Settings>Mail, Contacts, Calendars>Contacts>My Info>?
I put my name on my iPad, and it says my name on her iPhone. I try switching it to her name on her iPhone and it switches to her name on my iPad.
Is this a Bug?
Can't seem to get it to stick.
You can't, iCloud is intend to be used by individuals using one Apple ID. It is possible to use it between multiple users but you will lose some functionality such as "my info".
