Roles are per-group. A user can be an Admin in one team and a Player in another. There is no global role switch — you change a role inside the group where you want it to apply. See How roles and capabilities work in 360Player for the full model.
Change a role as a top-level admin
Top-level admins can change anyone's role in any group, including parents, by re-adding them to a group with a different role.
Go to Management → Contacts.
Find the user. Use search or browse to locate them.
Open the contact card. Click the user's name.
Add to group with the new role. Click Add to group, pick the new role (Player, Staff, Admin, or any custom role you've defined), choose the group, then click Done.
Parents are a group-membership relationship rather than a role type, but the same flow assigns them additional roles when needed — for example, adding a parent as Staff in a team they help coach.
Change a role as a group admin
Group admins can change the role of any user already in their team or group.
Open the team. Go to the Team section of the group.
Open the user's menu. Click the ⋯ (three dots) next to their name.
Pick a role. Under Role, choose User, Staff, or Coach.
The role updates immediately for that group. The team menu uses friendlier labels — "User" is the same as Player, and "Coach" is the same as Admin.
