Acrobat DC doesn't allow to Ask for signatures for a document previously digitally signed
Steps to reproduce:
1. First I will make a PDF doc from a word doc.
2. So I now have a PDF file and I will sign it digitally using a digital certificate starting from the Certificates button from the right tool bar.
3. After the PDF document is signed I will push the Adobe Sign/Request Signatures button and instead of opening the screen where to input the e-mail address of the person I ask the signature from it displays the message in the attached picture.
If I use the web version of Adobe DC for the same document digitally signed, everything is working fine.
I used this functionality hundreds of times before on version 2020.012.20043 and it was working fine.
I reproduced this scenario twice with two of your colleagues from support watching my screen from distance. Each of them promissed to come back in 48 hours but none of them did. And I must say that I am kind of surprised to see that now I have to submit this bug report myself again.
