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!

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?
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.

Hi Uditerboard,

We're sorry that you've been experiencing problems with the Klarna app blocks. The availability of these app blocks can be affected by the theme used by your store, as not all themes follow the default Shopify architecture.

Our Merchant Support team will be reaching out to assist you with getting this set up for your store.

invisible for some reason. There are hard to get support! I have tried all of the guidelines without any solution. When you click on customize theme are they still there but not displaying. No where to find support, I send a email to without any response

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!
