Faulty save facility when updating cross references across a book
When using the update cross-references on the Book panel of CC2020, it opens each chapter, it then updates the references, but then asks you to save and overwrite the chapter that it has updated. Maybe this is suitable for some, but I find it is frustrating when you have to agree to the file's same name and then agree to overwrite when you have over 20 chapters to go through every single time I update cross-references.
CC2019 used to open, update and save the chapters without questioning you. Maybe this is an option I have missed under Preferences.
