A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Same issue here, just started today from what I can tell. Massive issues across multiple notebooks, including brand new created ones. Additionally, getting errors even opening a section when opening Onenote in a BROWSER using sharepoint hosted notebook. The same notebooks worked just fine locally and in a browser last week. Additionally, browser-based or teams based usage also was working fine.
