ICML export doesn't include <HyperlinkPageDestination> elements
(Affects all versions of InDesign that support ICML export)
Export the story in the attached document to ICML. Delete the story in InDesign and then re-import the ICML. The Hyperlinks panel shows "The referenced paragraph or text anchor is missing".
This is only a problem for the ICML export of internal links. Hyperlinks to pages in external documents are exported correctly. The information is also correctly stored when saved to IDML.
Thank you for reporting the issue.
