I've got the exact same problem, there is no sync whatsoever happening to Google Contacts/Gmail any more. This was working until very recently, and there hasn't been any change in the setup on my part.
The problem is not a generic CardDAV one. CardDAV is all fine and dandy when syncing to iOS, it's just the SOGo part that's broken. For the record, while Google will stop supporting CalDAV, I haven' heard anything indicating that they are pulling CardDAV support. It definitely hasn't happened and, for all I know, hasn't been announced. Cheers, Michael -- users@sogo.nu https://inverse.ca/sogo/lists
