Our entire organization has transitioned to Google, and will soon cease using MS products. Workfront allows Google assets (docs, slides, sheets, etc) to be uploaded, but doesn't support Proofing those assets. We have to download the Google asset into an MS asset, save, then upload in order to generate a proof. These extra steps are cumbersome. Our Compliance team expects the Workfront Proof to be the final record of truth when they approve a request.
