Dynamic Scaling of instance is not working after upgrading to ACS Version 4.19.1.2 from 4.18.2.4

Following a recent upgrade from Apache CloudStack (ACS) 4.18.2.4 to 4.19.1.2, I’ve encountered an issue with the Dynamic Scaling of Instances feature, which was functioning perfectly in the previous version (4.18).

I have verified all necessary configurations, including:

• Template settings
• Compute offerings
• Global variable "enable.dynamic.scale.vm" (confirmed as enabled)
• Instance settings (Dynamic Scaling checkbox is selected)

Additionally, I performed a fresh installation to rule out configuration errors, yet the issue persists. Despite thorough checks, the root cause remains unclear.

Could you please provide assistance to resolve this?

Thank you.
