Hello,

When trying to add tags to this specific PDF, I get the following message: Adobe Acrobat was unable to make this document accessible because of the following error.

Hi jbcidi

Apologies for the delay in response, I hope you would be able to fix it by now.

Please try to recreate the PDF file, Go to file and do Save As Adobe PDF.
