It’s too bad. After the new template was renovated, there was a Klarna installment module in the preview, but the website client couldn’t see it at all. It was a serious bug. There was no reply to the customer service email.

Thank you for your review! I can see our merchant support is currently helping you look into this as it would appear the placement requested is already visible on the product page. I recommend forwarding any further concerns straight to and we are happy to keep supporting you from there. Have a lovely day!

Hi, I am not getting any response from support please. Having issues with the application and no response. When trying to select a static page it only allows me to see a certain amount of pages in alphabetical order, and the search tool doesn't work. I am unable to attach to my page because of this.

Doesn't work. Even though I've installed the ad blocks in my theme, and they appear in the preview, they do not show up on the live site. I'm using the Dawn theme.

Thank you for your review. Depending on the settings in the app On-Site Messaging will show to customers located in the country that matches what is on your Klarna agreement used for the store. You can use for example VPN to simulate this. Checking your website now Klarna On-Site Messaging appears clearly using a US VPN, while when using a European VPN it would not which would be expected behaviour. If you have further feedback we would love to hear from you on

I have been trying to contact Klarna for well over a week now sending multiple messages to their support email. I try to sign into my karma account to finish setting it up and place the klarna sticker on my store so people know they have that option but I can't seem to get signed in to the klarna merchant portal to get help every time I try it says the password I set up is incorrect when it's not I've sent meant emails to get a password reset or any help at all on this matter with no response ever. How do you expect people to use this app when there is a option for help but no one checks it or contacts me to help me with the issue at hand

When I'm Shopify and editing, the Klarna symbol appears. But when you go online to my website, IT IS NOT WORKING NOR SHOWING up. This is so strange. Also when I switch to Vintage Mode and want to place the icons manually, I can't even preview my own online store. It says in a text that Klarna is working on it, but it has been there for a long time now... So annoying. For me, it is working, but for others, I can't see the Klarna icon!

You used to be able to edit css of the element but for some reason it doesn't work with this app anymore.

If they make it so that you can add custom css to the element again I will change the review to 5 stars but for now its pretty bad

Hi! Thank you for your review. Do you mean customizing the placement itself? As this has not been a part of the app but is rather something you can do in the Klarna Merchant Portal. If you are experiencing any problems with this or have further insights to share on this we would love to hear more to improve your experience with the app. You can reach us on or Thank you in advance!
