Yes, @Yosca and @Pitty_Kitty I have had the social feature in my game for a few weeks now (I don't use it). It was there along with Mr. Toffee. Only the Mr. Toffee event has been removed.
With Mr Toffee being missing from Candy Crush Soda and the Chocolate Box giving errors in Candy Crush Saga, King seems to be having a few problems lately.
