Indesign 16.01
manual back-linking of endnotes: since indesign does not generate back links from endnotes in exported pdfs (unlike in epub), I made a manual backlink by defining a text anchor on the endnote reference in the text and hyperlinking the number of the endnote to that anchor.
After doing this however, if i then try to export as an epub it seems the manual hyperlink causes a conflict with the epub export, which results in the program freezing indefinitely requiring manual shutdown by ending task in Windows (10. 20H2)
