I develop a Power Automate flow and use Graph API to create OneNote pages. It works good. But recently I have started receiving an error: "The section has reached its maximum size and cannot have any additional content added to it." I have not found any limits on Microsoft documentation other than free space on OneDrive/SharePoint.
The notebook is located on user's OneDrive and the user has 50% (500 Gb) free space. Overall tenant free space is more than 500Gb as well.
So could you please advise what other limitations do we have working with OneNote via API that may cause the error?
