So I've added my Google account to the online-accounts in the system settings, but unfortunately Gnome programs like Gnome Contacts and California Calendar can't access any information from it. I read online that with the newer Ubuntu systems Gnome programs don't integrate with the configured online accounts, so I'm wondering what's the point of adding them if users have to import and export data manually. I've already tried a lot of solutions I found online regarding this issue, but none of them solved anything (most of the solutions were written for older systems and didn't work for Ubuntu 15.10). So I'm basically wondering if anyone has a solution for syncing Google contacts and calendar with Gnome contacts and California Calendar.
Info about my system: Ubuntu 15.10 64-bit.
