Hi guys. I have an issue with syncing my calendar between my iPhone 4 and my iPad 2. It's only come to my attention since I upgraded them both to iOS6. Basically, when I add an event on one device it no longer updates on the other device like it used to. I have tried on both devices and it doesn't work either way. Has something changed? I am also subscribed to a couple of group calendars. These are both on my iPad but no longer on my iPhone. Help please?
