Q: Incomplete Calendar/Contacts Sync Since Update to 9.2.1

On the release day a few days ago, I updated my iPhone 6S, iPad mini (3rd gen) and iPad Pro to 9.2.1 and my iMac and MacBook Pro to 10.11.3. Syncing of Calendar and Contacts works just fine between the two Macs and the iPad Pro. However, the phone and the iPad mini are not syncing these past few days. The iCloud calendar is syncing OK also.

 

All of the iOS devices have the exact same settings and using the same Apple ID and all have been continuously logged in. Ditto for the two Macs. Lack of sync to the phone is really annoying.   Is anyone else having this problem and know a solution?

iPhone 6s, iOS 9.2.1

    Try Settings/iCloud and slide off syncing. Wait a few minutes and then resync.

     

     

    Have you tried signing out of iCloud and then sign back in?

    Yes, I tried the turn off of syncing several times. I don't like the option of signing out of iCloud because it warns that all photos will be removed. I have close to 10K photos, so that is many hours to get the photos reloaded.

    GO FIGURE!  All of a sudden, sometime in the past few hours, the iPhone and iPad mini synced perfectly. I never signed out of iCloud on any of the several devices. My theory is that a third party app was the culprit. Why? Because the normal syncing began after I ran updates for about 17 apps on the phone and 11 on the iPad mini a few hours ago. Anyway, hopefully, problem solved.

    It happened again! This time only the iPad Pro synched OK. Went through all the steps that Apple shows at https://support.apple.com/en-us/HT203521 on all devices. No love.

     

    Then I noticed something in common with all of the non synching events. Yep, some events were synching OK and some not. Well, the common factor was that the non synching items were originally entered as an All Day event and I deselected All Day and entered start and end times. (I do that for an event that I know the day but not yet the specifics.) So, with a couple of such items, I deleted the converted event and then re-entered it from scratch. Voila!

     

    I can now go through and fix these. At the same time, one wonders if I found a bug that Apple needs to work on. I have been doing this for a long time. This behavior began with the update to iOS 9.2.1.
