I'm investigating a price/currency mismatch in a TestFlight app. Environment: iPhone 15, iOS 26.6.2 App version 0.4.2 (Build 47), distributed through TestFlight Consumable product ID: line_stamp_8pack_1980 Diagnostic comparison: October 5, 2026, at 11:22:47 JST (UTC+09:00) For the same product, all three product lookup paths returned price 11.99, currency USD, and display price $11.99: StoreKit 1: SKProductsRequest / SKProduct StoreKit 2: Product.products(for:) expo-iap: fetchProducts The direct StoreKit calls were made through native Swift diagnostics in the app. All three lookups succeeded without errors. StoreKit 2 reported storefront country USA and ID 143462 before and after its lookup. expo-iap also reported USA before and after its lookup. StoreKit 1's storefront was unavailable before its request. Afterward, it reported USA, with storefront identifier "143462-9,29". Our diagnostic initially labeled this as a storefront change, but an unavailable-to-available result does not establish an actual country change. During the same testing session, Apple's purchase confirmation sheet for this product displayed ¥1,980 and stated that the purchase was for testing only. I canceled the sheet without completing the purchase. The Media & Purchases account's country/region is Japan. App Store Connect pricing for this product is ¥1,980 in Japan and $11.99 in the United States. What could cause the product lookup APIs to return the US storefront price while the purchase confirmation sheet displays the Japanese price? What additional diagnostics should I collect to identify the cause and obtain a product price consistent with the purchase sheet? Thank you.

In my TestFlight app, StoreKit reports the Japan storefront (JPN, ID 143462), but product prices are returned in USD. Environment: iPhone 15, iOS 26.6.2 TestFlight version 0.4.2 (build 52) Product ID: line_stamp_8pack_1980 Product type: consumable Feedback Assistant report: FB25133058 Steps to reproduce: Sign out of the regular account under Media & Purchases. Sign in to a Sandbox Apple Account configured for Japan under Settings > Developer. Launch the TestFlight app and request product information. Expected result: The current Japan price configured in App Store Connect is JPY 1,980. The base country is Japan, and no future price changes are listed. Actual result: Storefront country: JPN Storefront ID: 143462 Product price: 11.99 Currency: USD Display price: $11.99 StoreKit 1 priceLocale: en_US@currency=USD I compared native StoreKit 2 Product.products(for:), StoreKit 1 SKProductsRequest, and expo-iap fetchProducts. All three returned the same USD price without errors. The storefront remained JPN before and after each request. The issue persists after restarting the app and rebooting the iPhone. No purchase was performed. What additional diagnostics or configuration checks would help identify why the product currency differs from the reported storefront? Is there a supported workaround for testing Japanese prices in this situation?
