Hi, I'm running stock 2.3 on my HTC Incredible S. The calendar app won't sync, either to or from my cloud calendar. 3rd party apps are the same. I've tried Jorte, aCalendar etc, and they will pull calendar data on the first time running, but after that it won't sync, either up or down. I've tried clearing the cache but nothing's happening. I didn't have this problem when I was running Nik's Jellybean ROM.
