Confirm that you accepted the invitation while signed in to the intended account and that the team now appears in your team switcher. Receiving an invitation email is different from completing acceptance.
Ask the team owner to check your membership and assigned role. A role can allow access to the workspace while hiding owner or administrator actions. Refresh the Console after acceptance and select the team explicitly. If the owner sees you as a member but access still fails, send support the invitation email address, team name, time, and visible error. Keep the invitation token and sign-in credentials private.
