> Afaik, you couldn't directly add CardDAV URLs in jessie either. Perhaps not under gnome-contacts, but on jessie the official calendar app seemed to be evolution, insofar as when I said "open calendar" from the top bar to get at my contacts, evolution is what started up, and that supported CardDAV.
> What you can use is gnome-online-accounts, same as in jessie. Oddly my remaining jessie machine doesn't have gnome-online-accounts installed, but handles CardDAV fine via evolution anyway. On stretch gnome-online-accounts doesn't present a WebDAV option, and trying the ownCloud option I have no idea what to type since it just asks for a server, not a URL. Previous attempts at entering a URL there failed. C.
