Calendar sync hang-up iTunes/iPhone
This used to happen years ago and was fixable, but now, after iTunrs updated itself to 12, it again hangs when trying to sync calendars. I have tried the usual tricks of checking/unchecking the wifi and auto options, but nothing fixes it. All searches bring up threads from years ago. Is it a new bug and/or how do I fix. Thanks.
iPhone is 10.3.3, iTunes is now 12.7.2.58, El Capitan is 10.11.6
