A StoreKit configuration file only verifies the local product configuration, so I would next test with the scheme's StoreKit Configuration set to None on a physical device/TestFlight build and log the exact identifiers returned by Product.products(for:). Also verify pricing/availability, Paid Apps agreement, and that the first subscription/IAP products are attached to the submitted app version. If the products remain selectively absent, collect a sysdiagnose and file Feedback Assistant because it may be catalog provisioning. I offer a focused 24-hour StoreKit/App Store Connect diagnostic if you want someone to review the configuration and logs and separate developer-controlled issues from Apple-side failures.
