I've just had our first few orders come in with the new Amazon "Login and Pay" method. This really looks _great_ as a customer experience on the checkout page!
However, things aren't quite as smooth for us after the transaction.
In the Amazon Seller Central, the successful orders are listed as status either "open" or "closed." It's not obvious at all what the difference between these orders is-- why should some orders be created in the "open" and some in the "closed" status? (In both cases, the full amount has already been collected.)
Side issue: None of the ones created in the "open" state can be closed.
Bigger problem: All of these orders (open or closed) still show as "pending" in FoxyCart. I believe that I have set up the IPN correctly, but is there something else that needs to be done? We have customers asking for their receipts, and we don't have them.
