PDF/UA identifier missing (Acrobat Pro DC)

Kenny Moore of TaggedPDF.com presents a suggestion for resolving the PDF accessibility error "PDF/UA identifier missing", using PAC 2 and Adobe Acrobat Pro DC.

Nice comprehensive explanation but unfortunately this fix is no longer available in the current Acrobat Pro version (2024).

My PAC 2024 report did not flag this, but when I try to assign the "PDF/UA v1 ISO 14289-1 2014" selection to the Accessibility PDF/UA compliance dropdown in the properties window, I received an error "The given metadata was not in the XMP format". Would you be able to assist?
