I’ve been doing some testing of Quick Note on iPadOS 15 PB.
So far the only apps I’ve found where the content link can be automatically added when you create a new Quick Note are:
Books - links to book but not the page
Messages - links to conversation but not the individual message
Podcasts - links to the precise timestamp as well as the episode
Photos - links to individual photos but link title is just Recent photos; Albums link with the title; memories, people and places don’t link
3rd party apps:
Pocket - saves links but with no title or other identifying info.
MLB - team links work correctly; news stories save link title correctly but with generic mlb news URL
All of the above reopen in the source app (I don’t think this is b/c of Quick Notes per se but b/c of the installed apps registering the URLs).
Chrome - saves URLs but they open in Safari.
The only app where the note pops again when you return is Safari.
Apple apps which don’t work at the moment:
