Issue during sync notes between Samsung Notes and OneNote

Lumacher I too am having a problem with Samsung Notes syncing with Microsoft OneNote.

I had a load of old Notes from a previous old device, opened Samsung Notes on my Galaxy S9 and it imported all my old notes  (Fantastic!!! thought i'd lost them).  The app then prompts to say it can sync with OneNote so I enter my Microsoft Account, select the folders and hey presto, one thinks it has synced.

I log into OneNote using Chrome web browser and there is nothing.  Open OneNote app up on my Galaxy S9 and nope... nothing.  So I open the OneNote 2016 app installed on my laptop and guess what?  Yep, you've guessed it.... NOTHING!!!

Seeing we are all posting about this issue in December 2020, it would suggest to me the problem lays with Samsung and maybe has something to do with one of the recent Android updates we've all received?

Question is how do we fix this?  Who is responsible for fixing this without Samsung and Microsoft constantly blaming each other?
