Digital Sigs in Pro Office

A digital signature I have on a PDF is not showing in DT Pro Office. Is this normal? If I open the file in Acrobat it shows up.

Does the Preview application show the signature? As DEVONthink is using the PDFKit framework, the results should be usually the same.

No it doesn’t. Hmmm.
So what’s the point of an authorized digital sig if an app the OS provides can’t even show it? Is this another outcome of the Apple/Adobe pissing match?
