A coach cannot see a team
Almost always membership, occasionally the session.
Gestionnaires- Are they on that team? Access is granted by team membership. Open the team's Coaches & Staff tab and look. If they show as Pending, the invitation was never accepted.
- Did they accept as the right account? A coach with two accounts may have accepted on one and be signed in on the other. Check the email address on the roster against the one they are signed in with.
- Right club? A coach at two clubs sees one club at a time.
- Do they need Team Admin? If they can see the team but not invite or remove members, that is the role, working as intended. See Team Admins.
- Sign out and back in. A role change is carried in their session; signing out refreshes it.
The message "You are not assigned to any team yet"
Unambiguous — they are on no team at all. Invite them.
Tip: Fix this by inviting them again rather than debugging. A fresh invitation is faster than working out what happened to the first one.
