The Recent Files workspace is missing
Adobe Photoshop, Illustrator, and InDesign
June 2017 and later releases
The File > Open (Cmd+O) command no longer launches the Recent Files workspace when the Show Recent Files Workspace When Opening a File preference is enabled.
Access a list of your recent documents by selecting File > Open Recent or through the Start screen.
Future updates to these apps may feature improvements integrating the Recent Files workflow better with the core user experience. Thanks for your patience as we work towards that optimal state.
