We've temporarily disabled sign-in record hyperlinks to previously signed guest documents. We expect the direct link to previously signed documents to be made available again this week.
These documents are still accessible in the sign-in record that first signed the document. To access this link, go into the guest history and find the sign in record where the document was first signed.
