I am using Acrobat DC to request electonic signatures on documents. Generally very successfully, but today ran into an issue where a signer name is being automatically retrieved from somewhere I can't control, based on the email address I enetered for a signer. I have a different name for the person associated with this address, and wish to change it but am unable to see how to correct the name.
Document is to be signed by "Jo Example" and I have an email address of email@example.com, so I add that email address as a Signer. However, the Request Signatures tool in the phase of placing signature blocks, it identifies this signer as "Sam Example firstname.lastname@example.org" I have no idea where the name Sam comes from, and would like to change it to "Jo Example" or let the signer specify it when signing.
