Hi Clayton,
Matthew here again from Stripe. Thanks for taking my call earlier, it was great speaking to you and I appreciate your time.
I understand that Klarna sources keep on failing and and I am glad we got to discuss this while on the phone. I had a look into this for you and managed to follow up on your previous requests to see what more I could find.
It seems that our specialists are currently working on the issue and you should hear from them as soon as they have an update. In saying that, I will bring some of the details that we discussed to their attention and I will highlight its urgency. They will reach out as soon as possible to assist you further.
