The affiliate program is available to every user within an active agency account in Senly — admin, manager, setter, closer or sales manager.
Every user automatically gets their own referral link and their own dashboard as soon as they open the Affiliate page for the first time. You don't have to register separately.
Exception: users who were accidentally created from a super-admin context lack a tenant link and can't generate a ref link. Ask an admin to recreate the user via /admin/users from an agency context.
