My boss has a problem. Some items in the calender are suddenly gone. Most of them were really important, so he missed his appointments. Now someone told us it has to do with the multitasking. He told us to remove the calnder app from the multitasking bar and start it up again. This should resolve the problem, but i cannot replicate it, because i already added his calender as a fresh one and most of the time the first weeks are going well. Does anyone has this problem before?
