Product Lookups and In-Store Availability Checks not working

Hello there!

I'm trying to enable the in-store availability checks functionality in C4C.

I've followed the instructions in the administration guide (edit scope for retail, assign roles, etc) and I was expecting the following:

"When you click on a product, the product details display. The Store Availability  tab displays the stores where that product is available with details such as the number of available items, the bay and aisle where they can be found.

Availability check can be performed across all stores of the same retailer."

Unfortunately, the Store Availability tab is not been shown inside the products.

Any suggestion?

Thanks.
