We just got the following issue when trying to sign a document in adobe reader with a A1 corporate certificate from SERASA RFB AUTHORITY.
"At least one signature has problems"
I saw some articles relating the step-by-step below:
And ok, it worked for me, but we must send the documento to some government agencies and obviously, we can't write in email message "hey, please, when open the pdf, do the follow steps".
So, is there any way to solve this issue?
Two months ago we had no problems like this with the same certificate.
