        Hi,
Google Calendar and Google Tasks are two different things. The 
Calendar uses CalDAV, while the Tasks use libgdata (since 0.15.1). 
There was a bug that the Google Tasks source was added even when it 
might not, which is fixed either in 3.12.8 or 3.12.9 (the current 
stable version is 3.12.9, while the 3.12.10 will be released the next 
Monday) of evolution-data-server.

Evolution cannot do the OAuth authentication on its own currently, it 
expects the token from the GNOME Online Accounts. That's the reason 
why users cannot add the Google Tasks source within Evolution itself, 
but will have it available, if they configure a Google account in GOA.
        Bye,
        Milan
