I am having the same problem. ON mobile devices it loads the mobile theme without the widgets but the page is the same as the desktop version. I can’t get it to load latest post either.
go to the store and add items to the cart less than $250.00.
go to cart and see if shipping is added to total
It isn’t working in Firefox or Chrome for me.
It does work in IE.
If an order is over $250 then shipping should be FREE.
