Sync problem with new Google calendar integration ZDC 8.0
I am using the new ZCS 8.0 CalDav integration for Google calendar. When I create the Google calendar in Zimbra through the wizzard it looks fine. All entries from Google calendar seems to be in Zimbra. But the calendar seem to be out of sync after a few time. When I delete the calendar (and clear the trash) and create new all Google entries are imported well again. A manually sync on right click is not available. Is there a other way to resync?
