It does what it says, allows placement of ads on product page, cart and home page. It doesn't allow a ton of customization around styling or configuring an explanation page.
The Klarna Merchant Portal now offers merchants the ability to customize the display options of their own On-Site Messaging placement, such as font size, link color, text alignment, border style, background color, and more. Customization made in the Klarna Merchant Portal will be updated on the storefront directly without any changes required in the Klarna On-Site Messaging app for Shopify (if the theme selected is the default theme). For more information, see: https://developers.klarna.com/resources/on-site-messaging/customization/
Easy to install and use. A bit limited as to where you can place the ads. I am guessing because the app is new there will come more options eventually other than only the product page or cart.
However, there is still a big problem with Klarna as a payment service when using Shopify: ONLY customer that are from the same country as the Shopify store can actually use the Klarna payments. It's because they have to be using the same currency as the store.
So for example if someone from Norway tries to pay using Klarna in a Swedish Shopify store (that is using Swedish Krona as currency) they will not be able to complete the purchase, and instead get a message that "this payment option is not available" (without any further explanation why). This needs to be fixed.
Therefore this application is just confusing customers from other countries because Klarna actually doesn't work for them... Otherwise the app itself was nice and I'm excited to see more features! 4/5.
Alternative payment gateways, like the Klarna Payments gateways, are processed using a single currency: the store's base currency. While Klarna Payments can support many currencies, the Klarna order must be in the applicable currency for the customer's address. Shopify's multiple currency functionality applies to orders using Shopify Payments (per https://help.shopify.com/en/manual/payments/multi-currency), For Shopify Plus stores, custom scripts can be written to hide payment gateways based on the cart's presentment currency, for more info see the Multi-Currency section at http://cdn.klarna.com/1.0/shared/content/integration/guide/US/Shopify/KlarnaPaymentsonShopify-MerchantGuide.pdf
