I've followed all the Ejunkie instructions for setting up a Google Checkout, and during testing all was working fine to start. This included the Google 'Thank you' page, which had the yellow box and link to 'Click here to retrieve your purchase'. This took the buyer to the Ejunkie thank you page with download link. All good so far.
Without any apparent warning, this yellow box is now not appearing, and the Google 'Thank you' page now just says to 'check the Google checkout order receipt for further instructions'. The receipt does have the download link, but it's not nearly as seamless a process as before.
Any suggestions why this should be, and why the process should have changed apparently by itself? I've trawled through the Google help section, and my head's spinning as a result. Could it be anything to do with optimistic and pessimistic payment processing by Google?
Thanks in advance
George
