Form tab order not preserved in PDF

I just made some changes to an existing form (moved fields around, added new fields) and reset the tab order before exporting to PDF. The tab order used to be retained in the PDF and now suddenly, it’s all over the place. I searched on past topics and see that this has been an issue on and off. I am on Windows 11, using the latest LibreOffice version. I checked the order again and ensured all fields are visible. Any ideas welcome.

Edit: The tab order works when the PDF form is viewed in a browser, just not in Adobe Acrobat Reader.
