I had the fullscreen button enabled for my game but have since removed the option and saved it again. However, the fullscreen button still appears on the game.
In addition to this change, I have also enabled 'Click to Play HTML5' in my profile but that change hasn't flowed through to the live version either. Does it usually take a little time for the changes to flow to the game? Its been about an hour, I'm not sure if I'm jumping the gun testing it too early.
