The new Mobile Store makes it possible for customers viewing your Online Store with a smart phone to be redirected to a mobile-friendly version. This will enable the customer to view your Online Store without the need to zoom-in to certain elements of the page, and generally results in a more pleasant shopping experience. When this option is disabled, the customer's smart phone will continue to use the standard Online Store, which is normally seen on a standard desktop or laptop computer.
If you choose to use the Mobile Store, please enable the feature at Layout/Mobile Layout in the Order Management System, and carefully review the layout parameters provided to create the best possible experience for your customers.
