Re: Express Checkout - no address at all
We just had the same thing happen to us. Order paid via PayPal express, no address sent back to the cart.
I do have the debugging logs turned on, but didn't see anything unusual in those (other than a lack of an address).
The payment email we received from PayPal was different than a normal one too. It looked more like when someone just sends you cash directly from within PayPal and in the details it said "Please keep this number for future reference, as your customer doesn't have a PayPal Transaction ID for this payment."
Cart is version 1.3.9d
Payments/orders prior to this came through fine.
I'll finish that project tomorrow, I've made enough mistakes today!
