Here's another September update coming up for you.
This trigger allows you to add a person to a flow when a specific field's value changes to any different value.
Choose a specific field. When the field is updated to a value different than the current, the person will be added to the flow. For example, if the Country field is changed from "US" to "UK", the person will trigger this step.
Then, connect the trigger step to an action step.
