Уведомление в Орео работает иногда, а иногда нет

Question

Я работаю с уведомлением в приложении для Android

Уведомление работает отлично в любой версии под O.

В Oreo его иногда (Отображение / нажатие) работает, а иногда нет, Когда язакрыть приложение полностью его работу, а также если я заблокировал устройство ... но не более 5 минут после закрытия.

Я делаю все, что видел .. Я ставлю разрешения:

   <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission  android:name="android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS"/>

и я работаю с JobIntentService

также я проверил SDK VERSION после уведомления о сборке ...

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) 

также я установил канал уведомления:

NotificationChannel mChannel = new NotificationChannel(CHANNEL_ID, name, importance);

но все, что ничего не меняет ...

Я не знаю, что мне делать.любая помощь, пожалуйста, и спасибо.

мой код:

Методы уведомления IntentService:
