    Adobe Reader DC signature validity UNKNOWN


      Hi Adobe,


      We are struggling with getting Adobe Reader DC to recognize signature as trusted.  Every time we click on a signature, we get this message in Reader DC, and cannot further sign a document.




      If we use Acrobat Pro 2017, we get the correct message:



      We have tried various settings under EDIT -> PREFERENCES -> SIGNATURES -> VERIFICATION (More...) and unchecked "Require certificate revocation checking to succeed whenever possible during signature verification", also unchecked "When document has valid but untrusted signatures, prompt to review and trust signers".


      Nothing seems to work, just odd how Acrobat Pro 2017 works and Adobe Reader DC does not.  This is happening to multiple users in our environment.


      Thank you.
