Not sure why it breaks in #[3] and #[2] and if note1 is affecting the preview. For me, adding nostr: as the prefix, the quotes are previewed and linked to the original note on those mentioned clients.
Yes - note1 is the older way of referring to but it does not mean it’s not better: https://github.com/irislib/iris-messenger/pull/383#issuecomment-1530116617

They have removed the support (or it was never there). Not sure why. It does not make the UX better if you need to add nostr: to every noteid. If you copy the noteid from Damus it comes without the nostr: so you have to manually add it.
That is currently the case, that you need to manually add the prefix to quote and show a preview for the clients mentioned.
