Allow returning customers to browse (Unauthenticated customer)

Go to System → Settings → Checkout

When enabled, this setting allows unauthenticated customers (visitors who haven't logged in) to maintain their shopping session from previous visits. This means a returning customer can continue to: Browse products and navigate the site. Add products to their cart. Add products to their wishlist. This feature minimizes customer effort by letting them continue shopping immediately without the hassle of logging in every time.
