I have a signed PDF document, which I need to be authorised converted. According to Acrobat is the document signed with valid signature and there are no changes after signing. (So i can't view and save the signed version). But the clerk who is doing the conversion, claims that there are some changes after signing and the document can't be converted. I told him that there are no changes according to Acrobat. And he told me, that Acrobat can ignore some "small changes in the pdf code" but his software for conversion can't.
My question is: is it possible that Acrobat can ignore "small changes after signing" and confirm it as signed nonedited version? Or is it a nonsense and only incompetence of the clerk or his software?
