Common Klarna problems and how to fix them

Payment or installment plan

Manage due dates and view your plan in the Klarna app under Payments; pay early any time to free up your limit.

Refund or return

Once the store processes your return, Klarna pauses and adjusts payments; if a payment is due first, use 'Report a return' in the app.

Account login or security

Reset your password in-app and enable 2-step. Klarna never asks for full card details or codes by phone.

Klarna Card question

Freeze the card and view transactions in the app; disputes start from the specific transaction.

App technical issue

Update the app and re-login; clearing the cache resolves most loading problems.
