How to Fix PDF Comment Formatting Changes During Shared Review
Question details
Users experience issues where comments, sticky notes, and highlights in a shared PDF change position or lose formatting when opened by different reviewers.

- Product
- Device & OS
- not provided
- Scenario
- Reviewing a shared PDF document collaboratively through SharePoint or Document Cloud.
- Observed behavior
- Sticky notes and highlighted text annotations move to the bottom-left corner or lose their highlights when another reviewer opens the file, disrupting the review process.
Ensure that all reviewers have saved their most recent comments and synced the document before troubleshooting. It is highly recommended to create a local backup copy of the original PDF file to prevent any accidental loss of existing annotations during the diagnostic process.
Verify PDF Reader Version Compatibility Across Reviewers
Incompatibilities between different versions of PDF software can cause annotations to shift or lose formatting.
When multiple users collaborate on a single PDF file, differing software versions can interpret annotation coordinates incorrectly. This typically results in comments defaulting to the zero-coordinate (the bottom-left corner of the page).
Open your PDF application and navigate to the 'Help' or 'About' menu to check the current version installed on your device.
Ask all collaborators to verify their software versions and update to the latest release if they are using outdated builds to ensure consistent coordinate rendering.
Ensure everyone uses the same designated platform, such as Document Cloud or the specific SharePoint integration, to open and sync comments rather than downloading and re-uploading the file manually.

Isolate the Issue Using a Local Sample File
Determine if the formatting issue is caused by document corruption or the SharePoint environment by testing a new file.
Use WPS Office for Reliable PDF Commenting and Sharing
WPS Office provides a robust and highly compatible PDF editor that ensures your comments, highlights, and annotations stay exactly where you put them. It seamlessly supports standard PDF annotation formats, preventing formatting shifts during team reviews.
- 1. Open PDF in WPS Office: Launch WPS Office and open your shared PDF file using the 'Open' button on the homepage.
- 2. Add Annotations: Navigate to the 'Comment' tab to add Sticky Notes, Highlight Text, or Shapes accurately.
- 3. Save and Share: Click 'Save' and use the built-in 'Share' feature to generate a collaborative link or export the file with comments locked in place.

Frequently Asked Questions
Why do my PDF sticky notes keep moving to the bottom-left corner?
This usually happens when the PDF software fails to read the exact X and Y coordinates of the annotations. It is often triggered by version incompatibility between different reviewers' software or syncing errors within the SharePoint environment.
Can I recover PDF highlights that disappeared during a shared review?
If the highlights were saved before the sync issue occurred, you can often recover them by checking the version history of the file in SharePoint or your cloud drive, and restoring a previous version where the comments were intact.
How do I ensure PDF comments look the same for everyone?
To maintain consistent comment formatting, ensure all reviewers are using fully compatible PDF software, keep the software updated to the latest version, and avoid editing the underlying PDF structure while a shared review is active.
Is it possible to flatten comments to prevent them from moving?
Yes. If the review process is complete and no further replies are needed, you can use the 'Flatten' feature in your PDF editor. This merges the comments into the document's base visual layer, making them permanent and preventing any further shifting.
