Cart response missing customer detail
Currently, I am attempting to retrieve Customer information from the BuyerIdentify using the Shopify - Storefront API - Cart Query on the server-side. However, I encountered an exception during the testing phase. I have two test stores, A and B. When I retrieve the Customer information from the Cart without passing the key query parameter in the CartID for store A, I successfully obtain the Customer information. But when I authorize and retrieve information for store B, the user information is erased. Given that the request parameters and authorization processes are consistent, I would like to know what might have caused the different response results. Thank you.
Test store A:
↑ Response correct
Test store B:
↑Response missing customer info
