If you're not getting survey response data there could be an issue displaying your survey. Below are steps to try.
If using Checkout Extensibility...
Add KnoCommerce Extension to Order Status Page
Go to Settings > Checkout > Customize to access the Thank You Page and Order Status Page customization interface. Within the Checkout Editor, make sure to select the Thank You Page or the Order Status page (not the Checkout page) as each page has its own editing screen and we do not have a survey block available on the Checkout page (see screenshot below).
Click the "Add app block" button in the bottom left and you should see the Kno extension listed there.
After you add the Kno extension, make sure to click Save (top right)!
