Not to nag, message

Every time I get the not to nag, but if you tell me your name, we can play together message, it won't let me enter a name. I click on the text box expecting to see the blinking | but it just plays a sound effect. It then comes up with a message saying if you change your mind just look for the King account symbol, but I don't see one in the game. This is not the first time this is happened because it has happened every time I get the not to nag message. I'm playing the game on king.com in Chrome.
