I find Google Calendars quite useful and I use them quite a bit. I have multiple calendars, one for personal items, one for my work, one for activities, etc. When I just got my Blackberry Storm and installed Google Sync on it, it worked perfectly fine and allowed me to sync all of those calendars. However, somewhere between upgrading firmware I realized that Google Sync stopped syncing any of the calendars except for the default.
Searching for answer on forums only lead to suggested answer:
Go to Google Sync > Options > Calendars and choose the calendar from the list.
The problem is that I had only one calendar on that list – Default Calendar (which is not even the name of my default calendar – it’s called Main Calendar)
I tried upgrading Google Sync, reinstalling it, resetting sync – nothing helped.
Just for kicks, I decided to sign into Google Sync using not my usual email, but the gmail email (which i’m not using, yet it was created, since i’m using multiple Google services). And voila! The calendar list got loaded and events from all of them synced!
Also, while in the process on the new firmware for Storm and Storm 2, it appears that Google Sync starts running in Compatibility Mode, which prevents people from being able to log in (user can type in the email, but not the password, and only portrait mode works), the solution there is to go to Settings > Applications > Google Sync and check Disable Compatibility Mode
Hopefully folks at Google will work out these bugs, until then, I hope this helps
