• Hybrid app (Vue 3 + Capacitor 5) with cordova-plugin-purchase v13 for Google Play subscriptions.
• App is installed from Google Play Internal testing (opt-in link). The tester account is added to License testing.
• In Play Console the subscription exists and has Active base plans (monthly/yearly). Availability is set to 173 regions.

Problem

• The app never receives products/offers from Google Play. No base plans are loaded, so I cannot obtain offerToken and cannot start a purchase.
• In logcat I only see Finsky lines like “Billing preferred account via installer…”, but I never see any BillingClient/ProxyBillingActivity logs when I trigger catalog refresh or purchase.

Logs

• Example logcat:
  • I/Finsky: [XXXX] Billing preferred account via installer for com.stablemanager.app …
  • No lines for BillingClient / ProxyBillingActivity even when pressing the “Buy” button.

What I expect

• After initialization, store.update() should return the subscription product with base plans/offers so I can pick an offerToken and call order(). When starting the purchase flow I expect to see ProxyBillingActivity and the Play purchase sheet (with Test card, always approves).

What happens instead

• store.update() leaves products empty.
• No BillingClient logs at all (only Finsky “preferred account…”).
• In this plugin version, store.on is not available, so I also tried a polling fallback (periodic store.update), but still no products.

Minimal code (TypeScript)

// init (after deviceready)
await store.initialize([
  {
    id: 'stable_manager.test.sub',
    type: Cdv.ProductType.PAID_SUBSCRIPTION,
    platform: Cdv.Platform.GOOGLE_PLAY,
  },
]);

await store.update(); // expecting products/offers here
const p = store.get?.('stable_manager.test.sub'); // returns undefined

// later, on button click
const payment = new Cdv.Payment();
payment.platform = Cdv.Platform.GOOGLE_PLAY;
payment.productId = 'stable_manager.test.sub';
payment.offerToken = '...'; // cannot get because offers are empty
await store.order(payment); // nothing happens, no BillingClient logs

What I tried

• Installed strictly from Internal testing (not via adb). Verified correct applicationId equals the one with the subscription.
• Tester account added to License testing; Play Store shows the same account.
• Cleared cache for Google Play Store and Google Play Services; rebooted.
• Waited >24h after creating/activating base plans.
• Created a simple Active base plan without any offer restrictions.
• Ensured Play Store/Services are up to date.
• Started logcat before opening the app; also filtered by process PID. Still no BillingClient/ProxyBillingActivity lines.

Environment

• Android, app from Internal testing track.
• cordova-plugin-purchase: 13.12.1
• @awesome-cordova-plugins/in-app-purchase-2: 8.1.0
• Capacitor: 5.7.8
• Vue: 3.4.21
• Google Play Billing client is whatever the plugin bundles (no direct dependency in my code).
• Product ID: stable_manager.test.sub
• Base plans: active, available in 173 regions.

Questions

1. Why would BillingClient never log anything when I trigger catalog refresh or start an order? Does this indicate the native billing client is not initialized/linked by the plugin in release builds from Play?

2. Are there known issues with cordova-plugin-purchase v13 where store.on is missing and products don’t populate on some minor versions?

3. What else can prevent products from loading despite:

   • app installed from Play Internal testing,
   • matching applicationId,
   • active base plans,
   • tester account properly configured?

4. How can I reliably verify (from logs or code) that the native BillingClient is actually created and queried in this setup?
