"Restore Purchases" button accessible and functional

Apple guideline 3.1.1 explicitly requires a "Restore Purchases" mechanism for all non-consumable IAP and subscriptions. Its absence is a rejection reason — but the practical impact compounds post-launch: users who delete and reinstall the app, upgrade to a new device, or restore from backup lose access to content they paid for. These users generate support tickets, file chargebacks with their bank or credit card company, and leave one-star reviews. Chargebacks damage the developer's payment processor standing even though Apple actually processed the payment. A functional restore path prevents all of this at minimal implementation cost.

Add a "Restore Purchases" button to your paywall and/or settings screen. The button must be reachable without completing a purchase — users who reinstalled the app have no other path to reclaim their access.

// PaywallScreen.tsx or SettingsScreen.tsx
const handleRestore = async () => {
  try {
    const customerInfo = await Purchases.restorePurchases();
    if (customerInfo.entitlements.active['premium']) {
      unlockPremium();
      Alert.alert('Purchases Restored', 'Your subscription has been restored.');
    } else {
      Alert.alert('No Purchases Found', 'No active subscription was found for this account.');
    }
  } catch (e) {
    Alert.alert('Restore Failed', 'Could not restore purchases. Please try again.');
  }
};

<TouchableOpacity onPress={handleRestore}>
  <Text>Restore Purchases</Text>
</TouchableOpacity>

Place the restore button in both the paywall and the settings/account screen. Verify that after restore, the entitlement state is refreshed and the premium UI unlocks immediately.
