Can't login with my KING account OR FB. I've tried all the suggestions. I've tried turning off cell phone data, tried updates and tried resetting - NOTHING. It says "can't find internet connection" or "unknown error". Bout to give up on King!
Have you tried the steps here:
Or maybe even try connecting with mobile data instead of internet, or vice versa.
