I am building a small workflow using Microsoft flow to auto move the Nintex status email from my inbox to a SharePoint list. I found out some advantages of Flows than Nintex workflows. First it support a debug button to either : replay the last trigger or halt the workflow and want for you trigger. The first on give us very fast debug speed. And the second is amazing, when I halt the workflow, then i send a email to trigger it, it runs instantly and show me error if has any, very fast debug way.
