Active Purchases (from Play)
Lists current unacknowledged / unconsumed purchases returned by
digitalGoods.listPurchases(). Use a row's Fill button to auto‑populate Recovery. Refresh after recovering to confirm it disappeared.Recovery ("You already own this item")
If Play blocks a new purchase with You already own this item, the prior token wasn’t consumed yet. Enter the productId and its purchaseToken then press Recover. You can obtain the token from a previous Test Purchase Result or server logs.
Expectations for success:
- paymentRequestInWindow = true
- hasDigitalGoods = true (for price fetching)
- sampleGetDetails returns an array with your product
- canMakePayment = true (optional but nice)
If hasDigitalGoods is false inside the TWA: verify Play Store Chrome up-to-date, origin verified (asset links), and app installed from Play (internal test track) with products active.
TWA Status Check: window.matchMedia('(display-mode: standalone)').matches = loading...
