Now flow users can see whether an input value in a flow screen component is invalid when the user changes the focus to outside the component. For example, the user enters a value for an email component. The component validates that the input value contains the right domain as soon as your user clicks another screen component. Previously, component validation error messages appeared only when you moved to another screen or finished the flow.
Where: This feature is only available in flows that run on API version 63.0 or later and not supported in Classic runtime for flows
