Let us suppose your flow is running on schedule. To make it more dramatic, the UI flow is running on schedule. The browser opens up, does some action, and closes it. Now, if you are in the middle of something very important and the browser doesn’t allow you to work. We can just cancel the flow run by following this simple step.
Go to flow.microsoft.com, open up your flow which is running. Down below, you will see your flow run in the past 28 days. If it does not show up the current running flow, refresh all runs.
Open the current running flow and click on Cancel.
