Why can't I play my King games on my tablet?? The screen goes back to home screen in middle of a game or won't even let me tap play. This started after the last update?

I do not play the games, but I checked, and the reviews on the Candy Crush page on the Play store suggest a lot of people are having similar issues after the recent update. I would submit a support request to the developer there are links and email address on the Candy Crush page on the Play store. The more complaints they get, the more quickly they will try to resolve the issues. Meanwhile, do you have the latest available firmware for the tablet? Most recent Tabs will automatically check for updates and let you know, but older tablets did not. You just had to check the manufacturer's support page for your product every few months.
