I have:

• configured subscriptions
  • 2 products each 2 base plans - every plan is active
• license testers
• internal track testers
• have the same build number in internal track as in my Android studio
• I did release build and installed it to my device via adb
• same signing keys
• I can list my subscriptions by providing skus

But unfortunately, I still can't get over the error when doing purchase:

error {
  "message": "That item is unavailable.",
  "debugMessage": "",
  "code": "E_ITEM_UNAVAILABLE",
  "responseCode": 4
}

I'm using react-native-iap library and this is my code(simplyfied):

  const {subscriptions, currentPurchase, finishTransaction, getSubscriptions, getPurchaseHistory} = useIAP()

  const subscribe = async (productId: string, offerToken: string) => {
    console.log('product id', productId, 'offertoken', offerToken)
    try {
      await requestSubscription({
        sku: productId,
        ...(offerToken && {
          subscriptionOffers: [{sku: productId, offerToken}],
        }),
      })
    } catch (err: any) {
      console.warn(err.code, err.message)
    }
  }

  useEffect(() => {
    const subscription = purchaseUpdatedListener((purchase: Purchase) => {
      console.log('purchase', JSON.stringify(purchase, null, 2))
    })
    return () => {
      subscription.remove()
    }
  }, [])

  useEffect(() => {
    const subscription = purchaseErrorListener((error: PurchaseError) => {
      console.log('error', JSON.stringify(error, null, 2))
    })
    return () => {
      subscription.remove()
    }
  }, [])

  const finish = () => {
    if (currentPurchase) {
      finishTransaction({purchase: currentPurchase, isConsumable: false})
    }
  }

...

{subscriptions.map((subscription) =>
              subscription.subscriptionOfferDetails.map((offer) => (
                 subscribe(subscription.productId, offer.offerToken)}
                >
                  {subscription.name}
                
              )),
            )}

• Do I have to release app to closed testing to be able to proceed with testing?
• Do I have something misconfigured?

Any tips&tricks welcomed🙏🏻
