Thanks for trying all those steps, and sorry it came to that.
That looks like a bug, which I’ve now logged.
I did a quick test of Hook + Scrivener 3 on Big Sur, and Copy Link from Hook window works. It yields the same URL as Scrivener yields when you choose Copy Document Link. However, Scrivener did not honour its own deep link: It opened the book (which is a good start), but not the specific chapter. But that is not what you’re seeing.
Have you tried a different book , potentially stored elsewhere, to see if it is something with that.
Can you try copying the document link in Scrivener itself.
Is there any reason why the Document Binder would not be visible? Could you try exposing it if it’s not?
I am still on 10.14.6 so…
Binder is exposed. Same message.
Made a new project on the desktop. Same message.
Copy link to document from within Scrivener yields :
x-scrivener-item:///Users/jk/Desktop/hook%20test.scriv?id=4107CA8D-44E1-44AB-8888-CA4B1D05D81B works as expected when I paste it in Notes and click on it — that is to say it opens the correct document in a new split editor which is slightly odd but ok.
But Hook doesn’t show a Copy Link menu item because it doesn’t know I have Scrivener open.
