Hello Oboenerd_VA,
Thank you for reaching Microsoft Community.
The Surface Duo launch required investment in our apps to ensure they could fully utilize the benefits of the dual-screen form factor. As we explored how best to do this for the Office experiences, we decided to focus our investment for Word, Excel, and PowerPoint exclusively in the Office mobile app. The Office app was designed to include the full Word, Excel, and PowerPoint mobile experiences, additional capabilities including the various PDF and Lens features, and an integrated experience that means fewer apps to use and requires far less storage on the device.
Kind regards,
StevenK
