I've been using Google Sync to sync my GCal and for the most part, it works great! I noticed today that I made calendar events on my BB but they didn't update to my GCal. It's set on Automatic sync (I double-checked) and even when I manually hit "Sync Now" it still didn't sync my new events. Also, I noticed that my sync hadn't synced since 4:00pm this afternoon.
Any help here? Why wouldn't it automatically sync and why aren't my events suddenly not syncing?
I haven't had problems with mine. Actually I have come to love google calendars! Never having to sync and always being in sync! Try a battery pull. See if that helps.
