'Allowed countries' configuration not recognised in Paypal Express Checkout for shipping address val
I have a client's shop allowing orders to a national shipping address only. Using the integrated payment method 'PayPal Website Payments Standard' the paypal express checkout can be completed using any country as part of the shipping address - though allowed countries are limited to the national one only.
That's not the expected behaviour, is this a misconfiguration issue or is this simply not provided by the paypal express integration?
Note: There's some module installed to preset the shipping country (to the national one) for each magento session - could that be related?
I couldn't find any issues similar to mine, and I would be surprised if that's unresolved - so would be great if someone can point me into the right direction.
