There are three possible roles in Cards: learner or editor or owner.
An editor has access to the dashboard and management, while a learner only has access to the course consultation. This is why you see the “Back to app” button in the header: this button allows you to switch from the “management” part to the “consultation” part. The owner has the same rights as the editor, but can also manage the workspace. To learn more about role management, follow the link below.
