I do use 2checkout shopping cart integrated into my e-junkie account and redirect people to 2checkout.com for payment. Once the payment is successfully processed, users gets sale confirmation along with download link of the product.
But this has not been case for my last three sales. I've sold 3 items but unfortunately, I had to provide download links manually since users were not able to get download links automatically right after the sale.
Do you have any idea what might be wrong? I've not changed any settings in 2checkout and e-junkie. So it just happened suddenly.
