I like this app and installed it on my store. However, it is not working at all. On-site messaging does not appear on my product page or any other page. It gave an error. I wrote to customer support via e-mail and the app messaging panel and waiting for the solution. I will review my comment and give 5 stars If the problem is solved soon. :) UPDATE. I have been contacted by Klarna customer service and told that the app is working properly within the geolocation of my store and currency. Thanks.

Hi Destina Home,
I see that one of our Klarna support agents replied back to you via your support case #24328551 earlier today and that On-site messaging is displaying on your product pages currently (for customers geolocated to the country matching your store's base currency).

For other locales, on-site messaging would be displayed, as documented at: https://docs.klarna.com/platform-solutions/shopify/on-site-messaging-app-for-shopify/faqs/#troubleshooting-why-isnt-the-placement-displayed-on-my-product-pages?

If you do need further help, our team at skosm@klarna.com is happy to help!

Fungerar inte, kommer inte upp någon ad. Antingen gör jag något fel, eller så fungerar den inte

Hi bolddesignz,
While I see that Klarna's On-site messaging app is installed, I don't see it active on your storefront yet. If you email our support team at skosm@klarna.com, someone can review the configuration to help. I've requested collaborator access to your store now to help this process go quicker. Hopefully our team can help get this working for you soon!

Unfortunately my experience in installing this app mirrors that of other reviewers. I had installed it but there was a glitch. Luckily the team responded very quickly and helped me sort it out immediately. It looks great!

I am a new customer of Klarna, I have done the whole account process at Klarna in which it was approved. So far so good, but after installing the shopify application I received a notice inside the application that does not support the Online Store 2.0, how so? all the themes of shopify today are in this new version and you have no support? seriously that? what a technology delay... And now how do I install and use klarna? I sent a message to support yesterday and have not been answered yet either... They have already started badly in several aspects to be a company would be. I hope they help me and that they improve this outdated and confusing system of yours. Translated with www.DeepL.com/Translator (free version)

We'll certainly support you via your existing support case; please know that our support team will reply as soon as they can, but that may be a few business days depending on the case load.

This app does support Online Store 2.0 though, as documented at: https://docs.klarna.com/platform-solutions/shopify/on-site-messaging-app-for-shopify/install-steps/#add-placements-online-store-20-app-blocks

Hopefully you can share the details of the notice via the case emails so that we can clarify that, and provide any other support needed.

Da migliorare, sono riuscito ad attivare il servizio solo grazie all'assistenza, molto rapida e preparata. Non è intuitivo e fluido il processo

I had some initial difficulties in making the installments visible in the product sheets. Klarna's support intervened immediately and resolved the problem quickly. Now everything works fine.

App is not working. Klarna is the worst company you can ever find, nothing is working and the support is really useless.

Appears to be working fine - no coding input required and the integration was seemless. Not sure what so many people are having trouble with looking at some other reviews!

Thank you WorldRaceCircuits for this great review! We're very glad the app works well for you.

We've worked hard to improve the app over time, with a major update relating to Shopify's improved theme architecture for Online Store version 2.0, which enables our app to integrate better with themes using App Blocks, and avoids many of the issues merchants had previously.

Thank you again for taking the time to share a review; we appreciate you very much!
