Same issue here.
I placed my order about 5 minutes after the release and didn’t experience any issues during the checkout process. I saw an order confirmation page afterwards, but unfortunately didn’t take a screenshot of the number but i see it on my payment provider (paypal).
So far, I haven’t received a confirmation email, and the order doesn’t appear in my account under “My Orders”. I also can’t find it using the order ID.
I contacted support yesterday, and they initially couldn’t find my order either. After some time, they told me they had “found it on a backup server”. He also told me my order items and price so they have the details. He mentioned that it might take some time due to the high volume on release day.
However, it’s now been more than 23 hours. :(
