I attempted to import several different OneNote notebooks and noticed the same behavior each time: notes in root sections (1 & 2 in image) are caught and placed in the main notebook (Notesnook Demo) rather than nested notebooks within Notesnook Demo. Some of these notes aren't placed in a notebook at all. Notes in the section group (sections 3 & 4) are completely missing in the import.
I have section groups within section groups and would like to maintain my organizational structure without having to recreate it!

EDIT: I have run some more tests and discovered that I get inconsistent results. I get incomplete sections (missing notes) in all cases and they differ slightly each time. I suggest adding an option to import offline OneNote exports as explained here: https://support.microsoft.com/en-us/office/export-and-import-onenote-notebooks-a4b60da5-8f33-464e-b1ba-b95ce540f309 This seems like the best way to ensure that everything is caught.
