A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
I found the suggestion from Randy elsewhere but on my Android OneNote there is no Remove option as long-press does nothing but suggest "click to open".
I found a way to remove them though which worked!
- Open OneNote on your desktop.
- Go to the Files menu and select Open.
- Scroll to the Notebooks section.
- Right-click and select "Remove from List" for those that you don't want to see.
- Manually sync notebooks on both desktop and mobile to update the list on the Android app.
