What issue do you have?

I would like to move from OneNote to Joplin, but import of OneNote individual folders and the complete database results in many of the notes incomplete, i.e., only the first few hundred characters of longer notes appear after importation. The OneNote export is complete, as I can import it into another OneNote folder and it is all there. More details:
Microsoft® OneNote® 2021 MSO (Version 2601 Build 16.0.19628.20166) 64-bit . The complete export file, Personal.onepkg, is 9.26MB; size certainly can't be a problem as a single .one export, which behaves the same way, is only 1.5MB.

Thank you for reporting this!

For reference: I've requested a sample .one file through a forum direct message.
