Signature Certificates are disappearing from the Adobe Identities page

[jsrco]

After updating to version 15.006.30279 our signature certificates are disappearing for the Adobe Identities page. This is prompting all of our users to create a new signature from file every time.  Some of our users have a usb token that has a certificate on it. This brings up the Sign Document tab where they can use the “Sign As" drop down and “Refresh ID” to get it to appear. But once they remove their token with the other certificate on it or restart Adobe, the problem continues.

Does anyone have any solutions?

This is a very old version of Acrobat Reader.

Bernd,

You are incorrect.  This is the latest version of Adobe Acbrobat Reader DC (Classic Track).  Adobe has two different tracks, Classic and Continuous.

I don't see this in your posting.

I have found that rolling back to a previous version does correct the issue. So is something with this update. In regards to 15.006.30279, it is not an older version. It was released as of yesterday.15.006.30279 Planned update, January 10, 2017 — Acrobat and Adobe Reader Release Notes

This same issue is also taking place on Adobe Acrobat DC v15.006.30279, not just Adobe Acrobat Reader DC.  Anyone have any insight?  Adobe engineers?
