Audi e-tron foil by Aerofoils review for Klarna On‑Site Messaging

I have done the whole account process at Klarna in which it was approved. After installing the shopify application I received a notice inside the application that does not support the Online Store 2.0! My theme is a Online Store 2.0 one nad i can add the placement in the backend but it does not work and it is not showing in the storefront. Please contact me.
