Android Firebase推送通知将在手机上发布，但不会在平板电脑上发布

我对firebase的推送通知有一个非常基本的设置，它在我的手机上运行良好。在3到6秒内我收到了通知。当我尝试在平板电脑上运行相同的应用程序时，我根本没有收到任何通知。谁能给我提个建议吗。
我使用的平板电脑是：
运行在安卓4.4.2上的联想标签2 A7-20F

这是我的代码。

Projectbuild.gradle

buildscript {
    ...
    dependencies {
        ...
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

apply plugin: 'com.android.application'
...
dependencies {
    ...
    compile 'com.google.firebase:firebase-messaging:10.0.1'
    ...
}
apply plugin: 'com.google.gms.google-services'

应用程序build.gradle

buildscript {
    ...
    dependencies {
        ...
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

apply plugin: 'com.android.application'
...
dependencies {
    ...
    compile 'com.google.firebase:firebase-messaging:10.0.1'
    ...
}
apply plugin: 'com.google.gms.google-services'

    }
}

更新 我在5-6小时后检查了我的平板电脑，看到了我所有的通知。也许是因为时间的安排。我仍然没有得到它，因为我没有安排任何通知。每次通知我都选择“立即发送”选项。如果有任何建议，我将不胜感激

更新

我试着连接不同的网络以防万一，结果证明这是因为防火墙。办公室网络安装了防火墙，我的家庭网络没有防火墙。即使在移动数据上，它也能正常工作

从更新gms和Firebase开始。这些文档应该会有所帮助。
