We are using the Klarna Checkout v3, which is working as expected except in one scenario.
Whenever a user cancel an ongoing Klarna payment session, the user is sent back to the basket, and verything looks good.
But at the same time a new order object is created, and the old one is still open.
Not sure if it is a big problem, but I can see that the shop is quickly filling up with abandoned order objects.
In this case (screenshot) I canceled the Klarna payment three times, and three order objects was created.
