What is the purpose of the Iteration review?

The Iteration Review is a regular SAFe Scrum event where the team inspects the iteration increment, assesses progress, and adjusts the team backlog. The purpose of the Iteration Review is to measure the team’s progress by showing working stories to the Product Owner and other stakeholders to get their feedback. The Iteration Review provides a way to gather immediate, contextual feedback from the team’s stakeholders on a regular cadence. The Iteration Review also allows the team to demonstrate their contributions, receive feedback to improve the solution, and adjust the Team Backlog based on new opportunities. References: Iteration Review, Iteration Review, What is Iteration review in SAFe® 6.0?, Iteration Review65
