Since the update to IOS 5.* I am missing appoinments in my Agenda on the iPad. Also appointments I make on the iPad are not synchronized to my Gmail calendar.
It worked fine for almost a year. I have about 7 agenda's connected through my Gmail account and using the Caldav account on the iPad. But since a few weeks, the sync looks random...
The iCloud is not enabled for the Agenda items, so that can't be the problem.
