I enabled IPN and auto return to merchant website in my preferences.
Unfortunately, after 10 seconds, the user doesn't get redirected on my website. He gets stuck on the message that tell him to go back to the merchant website. If the user click on the link before 10 seconds, he gets redirected to the same message.
It used to work before. It happens on the sandbox version as well.
It seems that this issue has been partially fixed. Now I get redirected after the payment but only to the default Auto Return URI set in my business account. I should get redirected to the URI set in the "return" hidden input field like it was before...
