Apple Notes is not intended for people who want to own their data and have control over export
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.
You just connect the account and turn on the notes synchronisation (right below calendar synchronisation).
Which PM comes up with this? And what does a developer thing when they implement this?
Just tested and embedded images do seem to be supported?
("insert photo" -> add photo -> photo is stored as a MIME part on the note)
I really wish Apple would revisit third-party server support with something more modern, such as a Markdown + file hosting backend (over WebDAV or whatever they currently consider the cool way of file sharing), but I'm not holding my breath.
