Acrobat Pro DC 2026 - Shared Review Toolbar doesn't show up

Fellows,

All of a sudden, after going through the Shared Review wizard (SharePoint being the server to store the shared file on), the PDF file gets the _review extension but the yellow toolbar with the Publish Comments button doesn’t show up in the PDF. Updated Acrobat to the latest version - didn’t help. Did anyone else encounter this issue recently? 

Thanks!
