This error message typically comes up when the email address invited to join a GitBook organization does not match the email address of the logged-in GitBook user attempting to accept the invitation.
Please contact the person who invited you and ask them which email address they used to invite you. If needed, they can invite a different email address instead.
This error typically occurs when a link, such as a sign-in or invitation link, has passed its validity period. For security reasons, these links have a limited lifespan.
If you created the link yourself (like a sign-in link), please initiate the process again to generate a new link. If you received the link from someone else, kindly request that they send you a fresh one.
This error usually occurs when the GitHub account that you use to set up the sync is already associated with a different GitBook user account.
