Can't share calendars after iCloud transition
Updated the whole family to iOS5 & iCloud today and it (almost) went off without a hitch.
My wife and I each maintain a personal calendar, shared (read-only) to the other. I also maintain a family calendar, shared (read/write) between us. Updating to iCloud broke the existing shares, but it told us it would do that, so once we were both upgraded, I reshared all the calendars.
My wife was able to subscribe/join to the two calendars I shared, no problem.
When I try to subscribe/join to her calendar, everything starts fine, but then at the very end, I get an error from the iCloud web page:
Can't join shared calendar
This calendar can't be joined because it's no longer shared.
I've tried recreating, exporting, importing her calendars, none of which has any effect. Even if I create a brand new calendar with no items and share it, that's the response I get when trying to join it. I suspect something in her calendar data on iCloud is messed up, but have no idea how to go about getting it reset.
Suggestions?
