To create a private league, tap on Leagues, then the + button next to My Leagues.
Add your league’s title, description, and logo. You can also decide whether or not to make the league public (you can always change this later).
Finally, it’s time to invite whoever you want. You can invite up to 50 people a day, so choose wisely!
Please note: In order to join a private league, you must receive an invitation.
