Bookmarks not working after SaveAs

Hi,  

I’m experiencing an issue with bookmarks after performing a "Save As" operation in Adobe Acrobat and wanted to understand if this is expected behavior or a known limitation.  

Scenario:

- I generate a PDF file, and the bookmarks work correctly.

- If I download/open the same PDF directly in Adobe Acrobat, the bookmarks continue to work as expected.

- However, when I perform a "Save As" on this PDF and reopen the saved file, the bookmarks are still visible in the bookmarks pane but no longer function (they don’t navigate to the intended pages).  

Observations:

- This issue seems specifically tied to the "Save As" operation.  

Questions:

1. During a "Save As" operation, does Acrobat rebuild or modify the internal bookmark destination references?

2. Is it expected that bookmark destinations (e.g., named destinations or object references) might be reset or broken during this process?

3. Are there any recommended approaches to preserve bookmark functionality when saving a copy of a PDF?  

Any insights into what happens internally during "Save As" would be greatly appreciated.  

Thanks in advance.
