I cannot access the Mobilities OLA 3.0 page
If you see an error message like "You are not allowed to access this page", you should check the permissions for your account in the "My Settings" section of the Dashboard. If you lack the "Viewing students" or "Managing Students" permission, you won't be able to access the students' lists.
If that is the case, contact your main institutional account holder for Erasmus Dashboard or International Relations Office asking them to enable those permissions for you.
