BUG: Product quantity not added to cart on mobile theme

Hi,

I've just encountered a bug on your live demo site:

Using a mobile device (or spoofing the user agent), go to a product page (e.g http://demo.smartsto...n/apple-watch-2) and change the quantity to anything other than 1 and add it to the cart.  Only one of the selected product is added to the shopping cart (regardless of the quantity specified).  Updating the quantity from the shopping cart page works fine.

Where is the code responsible for this?

Thanks for the bug report, which we recorded as an issue.

FYI: This was a simple fix in the Product controller (I think - don't have the code in front of me).  The form key string just needed to be tweaked to include ".AddToCart".
