I imported a “clean” PDF (i.e. without any annotations) into MN3 on Mac to perform a test.
I added a few notes (text excerpt + comment) but didn’t create any notebook or add the notes to existing notebooks.
After the test I deleted the document (local and iCloud), cleared temp storage and trashed bin.
Later the same day I reimported the same PDF and to my surprise the old notes (added during previous test) was there.
Where does MN stores that notes and how can I completely forget a doc and start afresh?
P.S. I know that I can quickly delete the old notes and add the new ones but my question is more on a conceptual level; I want to understand what’s going on.
