A large (1.5 gb) gmail account has been failing to synch completely with zd 2 beta 2 most of the day. I can send and receive email fine. The sync icon now spins for 5 min or something and then the error. A lot of the account did sync....not sure what is missing (calender is missing for sure, contacts are there, email not sure). A smaller gmail account seems to be ok.

Debug message: Unexpected tag in response(expected C231 but got C230)

Exception:
