Starting September 15, 2026, the Shopify admin has a new look, rolling out progressively to merchants. Apps that use Admin UI extensions and App Home UI extensions pick up the new styles automatically. Apps that render their own interface in App Home keep their current styles until you choose to move to Polaris 2.0.
