Which of the following statements about page actions is true?

The statement that completion actions are not triggered retroactively is accurate because completion actions are designed to respond to specific events in real-time when certain conditions are met. Once a visitor completes an action that triggers these events, the corresponding completion actions take place immediately. However, if a visitor had an earlier interaction without the completion action being applied due to timing, that action will not apply retrospectively to previous visits or interactions. Therefore, when a user's behavior or status changes, the completion actions are only relevant to the specific interactions occurring after the trigger conditions are established, not for past actions that have already been recorded. This distinction is critical for understanding how completion actions function in the context of tracking and engagement with prospects.
