I use Adobe Acrobat Reader DC 2015.023.20070. My problem is when I print a digitally signed statutory form (with the signature area showing "Signature Valid" and a green tick mark), the printed page shows "Signature Not Verified" and a ? (question mark) in place of the tick mark. The comments and forms selected is "Document and Markups", yet the print comes with a question mark.
Further, when I mail this pdf file as attachment, the recepient sees the pdf file with a question mark and a remark "Signature Not verified".
Can someone help me to get over these two problems.
Taking the email part: surely this is certain, until the recipient verifies the signature. You can't verify it on someone else's behalf.
