Just did the update on my Iphone 5s and am still having the same syncing problems. Can sync contacts from phone to computer but not in the other direction.
If I start an event on the phone and then add information to the computer calendar, I can sync in both directions for the whole day. I then have to start the process again the next day.
This is so frustrating. I guess I will call Apple and see if they have any new ideas.
I just don't understand why these problems keep persisting.
Syncing between iDevices is totally dependent upon the iCloud!
There are many issues related to this. While the concept is valid, the reality is quite different. Here are some things to know.
1- If both devices are TALKING to the cloud vi WiFi - i.e. both awake, not one "sleeping", then the updates will happen virtually instantly (depending entirely upon your ISP connectivity issues.
2- If one or both devices is TALKING to the cloud via Cellular connection, the delay can be significant.
3- If one of the devices is sleeping at the time an update is offered, it will not necessarily wake-up immediately and process the update.
4- If an immediate update is missed, Apple has some kind of "requeu" algorithm which takes some amount of unknown to me time to "try again."
However, there is an "issue" with contacts. It is possible to create contacts local to the device -- which do NOT get shared via the cloud.
If you Google for sync issues, you will find an assortment of comments.
I believe the same may be true of the Calendar, but I have not read about that.
