Somewhat inexperienced flow user here, moving from basic workflow design in SPD.
I am attempting to create a flow that updates a date field with the current date whenever a Person field is changed. I've done some reading in this forum and other googling attempts and it seems that using Switch is part of my solution, but I cannot figure out how to test for the person field conditions. The person field should trigger an action. The person field could be blank, or it could contain a value that would also trigger an action if it's changed.
