A financial services firm is implementing Dynamics 365 Sales. The firm has a strict hierarchical structure. A Sales Manager needs access to all opportunity records owned by salespeople who report directly to them, as well as records owned by salespeople who report to their subordinates. The solution must not grant the manager broad organizational-level read access. The system administrator has configured Managerial Hierarchy security. However, managers report they can only see records of their direct reports, not the records of indirect reports. What is the most likely cause of this issue?
