Same problem. Can not login or connect to internet in this game. Have tried all rebooting, clearing cookies, force resetting device - nothing works for two days now.
Thanks for tagging me @Spinnifix! It might be a server problem. Since @daniell7162 wrote her yesterday and you guys wrote her this morning then it's not resolved yet. Unfortunately, the office is closed today due to a holiday so no one will be in until tomorrow, Are you guys clearing the history? Do you all just login in with your King account? Do you have a Facebook account to see if it gets you in that way. If it does then it's definitely a King connection problem.
Let's try this. If you have an Apple device click here. If you have an Android click here. Follow the steps on those blogs and let's see if it clears up.
