Please add option to attach Onenote
Windows platform must include OneNote attachment and OneDrive. Thanks
We just pushed OneDrive support to the web browser app, reload the page to get the latest version.
You should now be able to attach OneDrive files to tasks and your project.
All the mobile apps should get this update sometime this week.
With today's update (version 2.9.0) you can upload OneDrive files if you use the Windows or Windows Phone app. Just click on the attach icon, then click Upload File. You should be given an option to upload a OneDrive file. We plan on supporting OneDrive from the web browser and other devices some time on the future.
