Select the PDF signature field you wish to remove a signer from. This will open the field editor in the right side panel.
Disconnect a signer from an individual field
If you do not wish to have a PDF signature field signed as part of a Workflow, you can disconnect a signer from any individual field. This will allow you to keep the PDF signature box as a placeholder for a signature, without removing the field. If you would like to disconnect a signer from all assigned signature fields, delete a signer from a Workflow instead.
