PDF with validated signatures is reopened and receive the 'at least one signature requires...'
Using Adobe Acrobat Pro DC.
I've created a PDF and sent to colleague for signature. We use 'certificates' to digitally sign. I also have his Adobe Acrobat FDF file (public key) on my computer.
When I open his signed version, I get the message that 'at least one signature needs to be validated'. I validate his signature and then digitally sign with my signature and lock the PDF. I save to a new file name. When I open the newly saved file with my signature, I get the ''at least one signature needs to be validated'. Shouldn't the validation be saved and no longer displayed as an error?
Maybe I'm misunderstanding digital signatures, but it seems like if I've validated the signatures on my end and locked the PDF, then that version is 'locked' in that state with the signatures associated with it.
Help!
Thanks!
