4. (Recommended) Set Include signature's revocation status when signing.
Embedding the signing certificate's revocation status in a document allows recipients to validate
certificates (signatures) while offline and speeds up the revocation checking process. Moreover, if a
certificate is revoked or expired at some time after signing, embedded revocation information enables
the application to determine if a certificate was valid at the time of signing so that the signature status
will remain valid.
Note:
Do not change the signing method unless instructed to do so by your administrator.

check.
