We finally got the time to upgrade from beta2 to beta3 of the ZCB last night. One thing that I've noticed so far is that the read status on messges no longer syncs from the Blackberry back to Zimbra. I didn't find anything on the forums nor in Bugzilla. Is this not a problem for anyone else. It worked in beta2.
Just to be clear.. If I read a new message on the Blackberry using beta2 it would show up as read in the web interface, but not vice versa. Now, neither way works.
The performance gain is unreal, by the way.
