Roger on that. Ok, so when I actually placed the order I was NOT signed into the site at all. I started from this page...

Shop freely.

... and then I paid a 60k sat invoice. After I paid the invoice, the invoice did not disappear, meaning perhaps the back end code did not see it as "paid"..... So in this case I might want to reach out to the merchant, which I can do at this "contact seller" URL:

..... When I go to that page, I just see a spinner, no content loads.... seems like it doesn't matter if I a logged in or not....

Also, how long was ithe page sitting on the invoice QR code waiting for confirmation? At checkout it says to not exit or refresh the page until the confirmation comes up, and it can take some time to confirm.

It shouldn't matter if you're signed in or not to place an order, you can pay without being signing in but won't receive a receipt. Your signing permissions are not set properly if the spinner is loading constantly (I for example just signed in on multiple different accounts with all the signing methods and I was able to view my past orders). What signing methid did you use to sign in (extension, bunker, nsec)?
