This article explains how to add and invite a player to your coach account when the player is paying for the subscription. If you are paying for the player's subscription either through a team or an academy subscription, you need to 'sponsor' a player.
Note: If you are trying to ‘sponsor’ a player, please use the ‘sponsor a player’ functionality.
To invite a player to link accounts, go to ‘players’, then click on ‘Invite new Player’. The player will be sent an email to confirm the linking of your accounts.
