Interesting. Did they add this feature recently? How do you set it up?
Embedded files (photos, video, audio, PDFs, etc.) and bullet hierarchies were the two things that I remember being the most trouble; you can copy bullet hierarchies from iOS Notes and paste them into another app, but they aren’t detected when copying the note via Shortcuts. Embedded files had to be manually saved. I think you could Airdrop notes to a MacOS device, but it would wipe the date created metadata from what I remember.
