Status Change trigger of a workflow

 In classic workflow, we have Record Status change among many other events those can be used to trigger the workflow. 

Though we have two fields for status change namely Status and Status Reason, trigger works only for Status, but not for Status Reason. In most cases this is actually record Deactivation or Activation. If you need to trigger a workflow for Status Reason we need to use Record Field Change event as we do for any other field.

Why talk classic Workflows, but not cloud flows/ power automate?

Previously we thought classic workflows will be history by now with introductions of Cloud Flows. Though cloud flows are pretty powerful in terms of collection of connectors we can use etc. Anyway, still its not helping the developers in many way;

• WF has Real Time option.
• WF got Custom Workflow Activity when need to switch to Code if need to pass a complex, Unit testable piece to code. 
• Connections/ connection refs of Cloud Flows are still messy
• WF is still easy to read. Illustration is compact compared to Cloud Flows require a big monitor to check even a small flow.

As per this writing, classic workflows still running in most of the implementations of the world and no sign of getting replaced that easily for a long time.
