Sometimes updating your game can fix in-game issues. To check what version of the game you're on, click the green gear icon in the top right corner of your screen to open your Settings menu. Towards the bottom of the screen, you will see a set of number that indicates the version. For example, the player in the screenshot below is on version 4.2 of the game!
