I am building an app which is making use of the new post purchase checkout extension. I've been able to build a basic extension and test this by placing an order. However, after refreshing the post purchase page a few times (I can't be sure of the number of times) I am redirected to the order status/thank you page and am not able to go back to the post purchase page. I then have to place another test order to see the page again and continue developing my extension.
I feel like I am missing something - is there a way to access the post purchase page for an existing order and keep refreshing so that I can fully develop my app without having to place order after order? If nothing else, I will run out of test orders in my store soon!
