Why can I not sync Yahoo Contacts in the new Yahoo app?

[AC Question]

I've downloaded the new Yahoo Mail app to my LG Volt (running 4.4.2). The new version of the app does not sync contacts (If you look at Settings -> Accounts -> Yahoo, all you see is "mail", whereas the prior version of the app had an entry for "contacts"). Do I need to revert to an older version of the app? Am I missing something? Thanks!
