Following the instruction to install the extension for magento 2.4.3 I came across an error when activating the integration. Once click integrate Magento 2 on the popup window, I was told the error message below. I double checked the API details are correct, and also the firewall Sucuri is not blocking Klaviyo. Anyone has experienced the same issue?
