I just upgraded my ZCS to Release 6.0.2_GA_1912. After this I've noticed that I no longer get my calendar entries on my iPhone via CalDAV. Oddly enough the phone doesn't give any errors and seems to connect fine. I can create events on the phone and they show in Zimbra but not the other way around. I even noticed that when I changed the "color" of my calendar that it correctly changed on the phone as well so I know there is communication happening, but I must be missing something.
Any help is much appreciated.
