Amazon is continuously improving the Account Health experience by making it easier for you to view and address all policy violations and defects affecting your account health in one place.
In the year 2019, Amazon has added Suspected Intellectual Property Violations, Restricted Products Policy Violations, and Customer Product Reviews Policy Violations to the Account Health experience.
In the past, Amazon has communicated these issues elsewhere in Seller Central, in your Performance Notifications inbox, or via email. Please take a moment to view your Account Health and address violations and defects in a timely manner.
