Hello,
Can someone else confirm that ?
Upgraded plateform from 2020.2.1 HF2 to 2020.2.4 and agent version 2.4.2.2229 (beta) to 2.4.4.2285.
On Windows 2008 x86 servers, the APM plugin, used by SAM module, disappear from agent :
- agent 2.4.2.2229 on a windows 2008 x86 :


Then I approve the update, agent is upgraded to 2.4.4.2285 :

After that, APM plug in is not listed anymore, and when I test from SAM application monitor :

Tried to uninstall, clean and reinstall agent, APM plugin still missing from C:\ProgramData\SolarWinds\Agent\Plugins folder and from C:\Program Files\SolarWinds\Agent\Plugins; and appliation polling does not work anymore
Tried to push it with SDK (-EntityName "Orion.AgentManagement.Agent" -Verb DeployPlugin), "APM" appears with version 0.0.0.0, then I approve update, and APM disappear
Thanks
