How to edit audiobook metadata in Books?
After upgrading to Catalina my audio books are a shamble. My whole collection of audiobooks have moved to the iTunes replacing 'Books' app. In the process many have been pulled apart into their separate chapters and I can't get Books to recognise them as belonging to the one audio book.
How can I edit the metadata of audio books (that were not purchased in the Apple audio book store) so that all these separate chapters are recognized and played as one book?
This question has never been answered with the upgrade to Monterey, still the same problem.
