Power Automate Basics - Update Child Records 

Before Power Automate, updating Microsoft Dynamics 365 Customer Engagement records from a parent record was a bit of a chore.
JavaScript, Workflow Assemblies, Plugins ... code-based solutions were the only way to meet the simple requirement of automatically updating child records when a change is made to a parent record.
In this video, we walk through step-by-step the creation of a Power Automate flow which updates Contact records under and Account, when the Account record changes. Along the way we cover simple concepts such as composing the Account GUID, using FetchXML to retrieve the child records, and the performing the update one each row that is retrieved.
