Klarna On‑Site Messaging

UPDATE: 10 days later I had a reply back although the person didn't know what the problem was. After highlighting that to them, someone else replied which didn't appear to know either but at least quoted Sara Nyrönen (Delivery Manager) in. Sara eventually replied and was very helpful.
Essentially, we created a Klarna account ourselves before Shopify coming up with its own integration. Due to the integration, I believe that a second account was created automatically behind the scenes, but Klarna couldn't detect the correct one to use.
Sara shared with us the correct Merchant ID which worked right away.
Hopefully this will help somebody, both help desk and customers.

PS. I don't know how it works now, 6 months later, but I believe the app should have at least a clear notification about this scenario and how to address it (e.g. raise a ticket with this specific request).

INITIAL REVIEW Oct 2024: Now that Shopify integrates directly with Klarna, https://help.shopify.com/en/manual/payments/shopify-payments/local-payment-methods/klarna , this app shouldn't require a Klarna account to be able to enable the on-site messaging on the product page. Without an account this is useless. :(
I have contacted merchant@klarna.com three days ago without an answer.

Hello, I received this message about my Klarna integration. See below: "The following versions of these third-party payments integrations are
not compatible with Shopify’s latest checkout. They will no longer be
available after July 31, 2022: Buy now, pay later with Klarna." How can I can the update to the latest integration?

Great way to surface to customers that they can break up their payments—especially impactful for our store since our products are on the premium and pricey side. The UI was a little clunky to use, but I figured it out after some tinkering. There are good customization options built-in.

Doesn't work anymore,everytime open it just say"An error has occurred".
No app block and be added in editor and even use the code snippets" " ,just flash the blurry klarna icon then gone?
Update:
A few weeks ago, they contacted us to manually install the code properly using the collaboration account. One star was taken away because of the late reply.

Very good does exactly as described once installed correctly and support is very helpful so recommended.

Placing the widget is always a little awkward but it gets the job done. The messaging that changes with order amount is nice on the cart page

The app is good but with paypal it cause a conflict and paypal button is not showing in the cart. I know it cause a problem because i contacted shopify support and they said that klarna is causing this issue, can anyone help?

This service will assist us in developing our business further and increase funnel as it provides multiple options of payment. In spite for customer service delayed reply; immediate support provided.

Desperately trying to get this app to work. Been messaging support back and forth over email and going backwards with no clarity :(

UPDATE: MARCH 2023
Dana from Klarna was in touch shortly after posting this review and has been amazing in going through and sorting out all issues with the app on store. I think there is unfortunately is a big difference between day to day level of support and higher level support. Klarna app now all operating smoothly as promised out of the box. Thank you Dana.

Ho usato ques'app per l'avviso agli utenti della possibilità del pagamento in rate, all'inizio ho avuto qualche difficoltà nel configurarla ma grazie al supporto rapido e gentile, son riuscito a configurarla nel migliore dei modi.
