Endnotes not accessible in InCopy
I finally figured out where the endnotes disappeared to when I imported a document from Word, only to find out that they will not link to the story text boxes and are inaccessible from InCopy. This adds all sorts of problems to our workflow.
Fix is available in version 13.1 of InDesign.
Please update to the latest version available to you via Creative Cloud Desktop application.
