We have 5 consumable in-app purchase products (Product IDs: localshadows_support_099, _499, _999, _2499, _4999) currently in "Prepare for Submission" status. Our app's first version (1.0) has also not yet been submitted for App Review.
Question: Does sandbox testing of these consumable IAPs require the app to be fully approved through App Review first, or is it sufficient for the products to be attached to a version that has been submitted (even if still pending review)?
What we've tried: We're using react-native-iap v16.4.1 for a real native StoreKit 2 purchase flow (not RevenueCat, which was masking this issue via its Test Store simulation mode). Calling fetchProducts() for these SKUs returns an empty array, and calling requestPurchase() for them results in an indefinite hang with no error.
We want to complete sandbox testing before deciding on our actual App Review submission timeline.
