I had iCloud set up no prob (confusing, but got it). Synced my gmail account with only one calendar, I'll call it Primary. That was mid-October.
Then around Nov 1st I added two more calendars, "Work" and "Misc" to that gmail account. So Primary, Work & Misc calendars are all under the same gmail account. Now when I do an iCloud sync, "Work" and "Misc" sync instantly, but "Primary" calendar has not synced since Nov 1st. Ive checked device settings for that gmail account it's set to sync all calendars. I don't get it?
errrrr, you know AP, I had it all typed out step by step in a post just in case someone else hit a hitch. And right before Submit my browser crashed. :/
Heading out now, can address more later, but two things I recall, if relevant:
That same gmail account is also the exchange account.
And I had to set up a mobileme account about the same time I did iCloud, so it might have been related?
Sorry that's vague, I'll rummage through later and see if I have notes or anything.
