Our technical team has identified a problem with the **3D Secure (3DS)** authentication flow within the Shopify embedded application. Because the 3DS verification is not functioning correctly, customers are unable to finalize their payments at checkout. If your store is affected, you can restore credit card processing by temporarily switching from the embedded application to our regular Shopify application. Detailed instructions for setting up and configuring both applications can be found on our [AltaPay Shopify Wiki](https://github.com/AltaPay/plugin-shopify/wiki).
