If Edits are made to a document in the Review step, either through the Edit Info form or by a new document being uploaded, you can compare versions by hovering your cursor over the document link and selecting 'Redlines.'
To download the most current version of the document, you can select the three buttons next to the document name and download as the current document type version, or as a PDF. This can be shared with the counterparty without sending a word doc.
To download a version with redlines visible, select Redlines, and enable 'Compare Versions' with the toggle button. You can also download the document from the Document Viewer window.
