Google Play是否会封禁许可测试邮箱账户？相关异常问题咨询

我已在Google Play发布应用，将部分谷歌邮箱加入许可测试列表用于应用内购功能测试，但碰到了几个异常情况：

• 部分测试账户可正常使用内购功能，部分账户却被封禁测试，调试时出现Service connection is disconnected信息，还会显示奇怪的「Google Play In-app Billing API version is less than 3」提示（已确认应用集成的Google Play API版本是6.0.1）。
• 存在部分账户起初能正常测试，后续被Google封禁的情况。

想了解可以查询测试账户封禁原因的渠道。

以下是处理购买流程的相关Kotlin代码片段：

private fun processPurchases(purchasesResult: Set<Purchase>) {
    val validPurchases = HashSet<Purchase>(purchasesResult.size)
    purchasesResult.forEach { purchase ->
        if (purchase.purchaseState == Purchase.PurchaseState.PURCHASED) {
            if (purchase.skus.contains(purchaseItem)) {  
                if (isSignatureValid(purchase)) {
                    validPurchases.add(purchase)
                }
            }
        } else if (purchase.purchaseState == Purchase.PurchaseState.PENDING) {
            Log.e(LOG_TAG, "Received a pending purchase of SKU: ${purchase.skus}")
            // Handle pending purchases, e.g., confirm with users about the pending
            // purchases, prompt them to complete it, etc.
            mContext.toast(R.string.msgOrderPending)
        } else {
            mContext.toast(R.string.msgOrderError)
        }
    }

    acknowledgeNonConsumablePurchasesAsync(validPurchases.toList())
}
