The expected behavior if a prospect refreshes the page after initially submitting the form with the "Always Display Form After Submission" setting enabled is that the form would be displayed on the page once again (B). This setting allows the form to be submitted multiple times by the same prospect, which is useful for fields that are set to always be displayed, such as reporting issues or comments. The prospect would not receive an error message (A), be redirected to a thank-you page , or see the thank-you content (D), as these options are not compatible with the "Always Display Form After Submission" setting.
