I'm testing my store, and my transaction always gets listed as "failed".
The only payment method I'm using is paypal. After filling out the checkout form, I am taken to paypal, where I log in, and make the payment, then eventually I go back to the store and I see the Thank You page, but I never receive the confirmation email from my store, so I therefore cannot know the download code for the downloads.
If I go to the "orders" page, I can see the transaction in the "failed" tab. I can then click on the email address to send a form email containing the download info.
Any idea what the transactions are failing and a confirmation email never gets sent? Could it be that the PayPal API has been changed, so it's not working with eShop?
