[German]A brief question to users of Trend Micro WFBS 10.0 SP1: Patch Build 2185: Have you experienced issues updating definition (pattern) files since the patch was installed?

At the beginning of December I reported about the new patch in the article Trend Micro WFBS 10.0 SP1: Patch Build 2185 released. It brings compatibility with Windows 10 version 1909 and a number of bug fixes.
Signature patterns are no longer updated
I became aware of a possible issue on German site administrator.de via a post from Toni Schmidt. Toni has installed last week patch 2185 on several systems and writes
Yesterday we got some feedback from users that the virus patterns have an old date. Even after the update the Security Agent says
Last update: 13.01.2020 (day before patch installation)
In fact, it is like this: If the clients were offline for a few days after the patch was installed, do not update the virus patterns after that. A manual update is "successful", but the version and date of the patterns remain the same.
This can be checked on the Trend Micro Worry Free Business 10.0 Security Server. There you can read the 'pattern version'. Clients that are online should have a current pattern version (the user indicates that it is currently 15.633.00, but may have changed).
While writing this blog post I saw that already on December 13, 2019, one day after the release of the English language blog post, this comment has been left with the same problem description. The affected person solved it by reinstalling the TM software.
A Workaround from Trend Micro
The relevant administrator then opened a support case with Trend Micro and reported the problem. The manufacturer was unaware of the problem, but then suggested a workaround:
On all client machines that have the issues of pattern files not updating, delete the old pattern files.
The pattern files for the virus scanner are located in the path for Trend Micro WFBS 10.0 SP1:

C:\Program Files (x86)\Trend Micro\Security Agent\lpt$vpn.6**
As soon as the old signature files have been deleted manually, the affected person writes, the update of the updated signature files works again.
