Active link to supporting PDF document during signing ceremony?

Hi there, Allowing dynamic content is a severe security risk, this is why OneSpan Sign have introduced flattening in the first place. Although we are working actively on providing more flexible content during Signing Ceremony, there's not a built-in capability allowing to achieve this use case directly. There's also one Enhancement Request asking for "Enable links on flattened documents during signing ceremony", but it's not yet on the road map. Besides depending on the production behavior change, two potentially workarounds we usually suggest to the developers: (1) You can make the material/document you want signer to acknowledge an "accept-only" document (guide here), this will also be recorded by our audit trail that signer has viewed and accepted the document. (2)Or you can add the material as an appendix without any signature at the last index, and mentioned in your real document that "refer to appendix for more details". Hope this could help! Duo
