Adobe Acrobat Reader DC - Fill & Sign - Read Only Copy

Hello,

we are using Adobe Reader DC in our company the function Fill & Sign combined with Adobe Sign.

We found out that something changed at Adobe in the last days and have no an issue.

In the past 

What we do and how it worked in the past:

Users are working with Adobe Reader and using the Fill & Sing Function. After placing the signature the document was sent to Adobe and the certificate was created and included in the document. The result with signute and included certificate was shown successfully for the user. During the process a new file resp. ready only copy was created and saved. After the process the user closed the Adobe Reader and reopened the signed document - Signature and Certificat was include - perfect!

Now the situation is different. The process for placing the signature and requesting for the certfificate works as well and signature and certifacte was shown. But after closing the Adobe Reader and reopening the signed file the certificate is not available. It seems that saving the ready onle copy during the signature process only includes the signature and not longer the cetificate.

To keep the certificate that user must do an additonal manual save action before closing the Adobe Reader to the same file or a new file name.

This is an issue and new behaviour.

Any ideas for resolving this?

Regards
