We’ve recently expanded our app to be compatible with checkout extensibility and are seeing a frustrating error on the thank you page. Our UI extensions are available in two places on the thank you page as well as two on the order status page. We have not had any problems with the order status page but the app blocks on the thank you page trigger erratically.
The two locations being used for the app blocks on the thank you page is above the ‘order status’ block (A) and then within the ‘customer information’ block (B). Sometimes both are visible, sometimes only A, others only B, and then there are times when neither are visible. If you use console within the browser’s inspect there is an error that says ‘order not found’.
The inconsistency is seen irrespective of device and browser (in other words, it happens at random across the board).
