If new features are released, sometimes they're not released for everyone at the same time.
In order to test things out and make sure everything is working fine, we require some tests first. Because of this, you might not yet have access to a specific new feature that, for example, your friend might have.
This is an automatic thing, that cannot be activated or deactivated manually, and it is usually related to specific metrics or statistics on the player's account.
Another reason why some players have different features is because they are using a Beta version of the game.

We really ask for your patience and understanding in case you are one of these players. And do not worry, we will inform you when our a update comes out!
