Here are the steps in order for you to add or connect to your child:
Start in the Profile view at the bottom right of your screen
Click on Profile settings
Under 'Edit your children' choose to add or connect to another child
✨IMPORTANT! Your child's name might already be in the team if,
✔️ A. another parent or guardian already added them
OR
✔️ B. if the player is older than 13 and manages their own account
If none of the above, choose "My child is not in the team yet" at the bottom
If A or B, select the child's name and press "Send Request" at the bottom. The other parent or guardian will approve this connection in their profile settings and vice versa.
