Klarnas campaign - uninstall, disable, delete

Does not apply to Klarna Checkout (KCO) because campaigns are activated automatically.

NOTE! This presupposes that you have registered for the Klarna Campaign and notified us of your Pclass ID for the campaign, which you will find in Klarna Online.

Ready campaign - It is deactivated automatically but it is your responsibility to check.
You can turn off the campaign yourself / check that it is deactivated.

Admin -> Pay and shipping -> Payment -> <Klarnas Campaign Name>
Uninstall or disable just as usual regardless of the payment method.
