iCloud Drive doesn't work after a system restore.
I've recently done a factory reset of my laptop and noticed that iCloud drive, though turned on in System Preferences, doesn't work. The iCloud Drive folder in Finder is empty and I can't save any iWork documents to the Drive either. I have the option though of saving it to com~apple~pages.
I'd ask Apple Support about this however for some reason their chat service isn't available for this request so I've gone here instead. Any help as soon as possible would be greatly appreciated.
