We are experiencing a critical issue where StoreKit 2 is returning empty products when using Product.products(for:), specifically on devices running iOS 18.4.

 This issue does not occur on iOS 18.3 or earlier.

 Steps:

 Created a subscription product (e.g. "upm1") in App Store Connect
 Confirmed the product is active, localised, and part of a valid subscription group
 Call the following Swift code using StoreKit 2:
 Task { do { let products = try await Product.products(for: ["upm1"]) print(products) } catch { print("Error: (error)") } } 4. Result: products is an empty list.

 This regression is blocking subscription testing on iOS 18.4. 

 Kindly someone please advise on a potential fix or workaround.
