When you join an organization, your membership in that organization will be associated with a particular login. In order to work with that organization's restricted data, you must have recently authenticated with the login associated with your membership. If you sign in to Redivis using a different login (for example, you signed in with your personal email, while your membership is associated with you academic institution's credentials), you'll be prompted to re-authenticate with the relevant login before you can work with restricted data.
