Hello,
We produce a qualified digital signature from Acrobat Reader and we have a different result during the validation process between Acrobat Reader XI and Acrobat Reader DC.
The first one manages to validate the signature and the second one generate an error (see below).
That is the same document, with the same signature and qualified certificate.
Like we use a Certificate Authority referenced into the European Trusted List, our qualified certificate uses the following QCstatement :
qcStatements:

We don't really understand why the same document produces different result during the validation process between the two versions of the Reader.
Is there a reason?
