InDesign Share for Review Comments Becoming Unmapped from Pins After Document Updates

Hi ​@franks65267173  and ​@joe806root, 

Thanks for reaching out and sorry to hear that you experience this. To help investigate this further, could you please confirm the exact version of Adobe InDesign you’re using along with your operating system details?

It would also be very helpful if you could share screenshots showing where the comment pins appear on the Share for Review web page, and then the corresponding location in the InDesign Comments panel/layout where they appear unmapped. This will help us compare how the pins are being interpreted between the web review and the InDesign document.

Looking forward to your update.

Yes, the "unmapping" pins in Share for Review remain a frustrating and persistent issue in 2026, often triggered by page reflows, reordering spreads, or even minor changes to master pages that break the coordinate anchors for comments. When InDesign can't reconcile the old layout with the new update, it dumps those pins into an "unmapped" or "orphaned" state, a problem compounded by the fact that the web version often shows the pins correctly while the InDesign panel fails to sync them. To minimize this, many in the community have pivoted back to the Import PDF Comments workflow—which is significantly more stable for tracking specific layout markers—or they ensure they never move or delete pages once a review link has been generated.
