FortiClient EMS Cloud 7.4.4 – Security Posture Tag OS Version(Windows 11 latest update) inconsistent

Hello Fortinet Community,

I Am experiencing an issue with Security Posture Tags on FortiClient EMS Cloud.

Environment:

• FortiClient EMS Cloud

• Version: 7.4.4 build 2034 (Feature)

• Client OS: Windows 11

• Feature tested: Security Posture Tags

• Tag type: OS Version

• Rule configured:

  OS Version = Windows 11 (Latest update within 30 days)

Issue description:
The posture tag is not applied consistently.
Sometimes the rule is correctly evaluated and matched, but shortly after, the same endpoint becomes non-matched, even though the system remains compliant (Windows 11 fully up to date).

Tag is matchedTag is not matched

Observations:

• The endpoint remains compliant (Windows 11 + recent updates)
• The tag Is sometimes matched, then later not matched without any OS change (always)

Questions:

• Is this a known issue or bug in EMS Cloud 7.4.4?
• Is There any workaround or recommended fix?
• Are there specific EMS or FortiClient settings that should be adjusted?

Thank you in advance for your help and feedback.
