Hello! We saw an error processing the timezone information on your
account.

We deployed a fix over the weekend, and hopefully that restored sync on
your account. If not, please tell us, and we will continue to
investigate.

Hello! Our apologies for the delay in getting back to you!

There was an additional timezone processing error in our calendar code,
revealed after fixing the first one. It was not as disruptive if
encountered on the older Google Calendar plugin, but on the new code it
upset sync.

We've deployed a fix tonight, and hopefully sync should be restored for
you.
