Are you an Instructor or Admin User who is unable to manage certain areas of Enrollsy? The reason could be you don't have permission. Each Instructor and Admin user has a role with certain permissions.
Instructors only have four possible permissions:
Edit Primary Account Holders (customer account information)
Manage Classes (can edit Classes assigned to and make enrollment assignments)
Manage Content (can edit Class Content for those Classes assigned to)
Setup Kiosk
See this support article for how to edit Instructor Roles.
Admin Users can have up to 29 permission. These permission are listed here. Only other Admins can edit Admin Users. Learn how to edit Admin permissions here.
