My invitation link does not work. What should I do?

Open You → Invite a friend and copy your link. If the old link has expired, Calsa provides a new one. Send the complete new link. The old one will stay expired. Your earlier invitations and rewards are kept. Invitation tokens last 365 days. Requesting your link after expiry creates a new token without deleting your earlier invitation history.

An expired or invalid link cannot attach the invitation to a new account. If the link still fails, contact support before your friend signs up if you want us to check the invitation. They can still start Calsa normally, but that visit will not be connected to an invalid invitation.
