This is because your club/league has not yet officially registered with MyClubtap and it does not have an active fantasy game of it's own on the platform. To get your club registration process started, please request your club to Signup as a Game on one of the Sports on MyClubtap.
For more information, you can also contact Vicky on 0425 882 907 or email getstarted@myclubtap.com
In the meantime, you can add a different fantasy game as your favorite and once your own club has joined MyClubtap, you can join your own club/league fantasy game.
