I know there is another thread, where people started posting about this, but the other thread is over 2 years old.
Since yesterday evening CET, orders made with Snipcart through our website are being processed by the payment provider, but no webhooks are called and no confirmation emails are sent (neither to us, neither to the client). Also, the product is still in the cart for clients that already made a successful payment.
I hope you can fix this as soon as possible.
