Ionic Onesignal getIds pushToken always null

Hello everyone.
I have an app with push notification using onesignal. When I registered the player ID with method getIds it’s always null for pushToken value see in a picture below (in this case i’am using xiaomi with rom china). But, if i use another device it’s not problem. Is there any issue with rom china in this case.

Here’s the code for get player ID with one signal :

constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen, public oneSignal: OneSignal) {
    platform.ready().then((res) => {
      if(res == 'cordova') {
        this.oneSignal.startInit(Env.APP_ID_OS, Env.GOOGLE_PROJECT_ID);
        this.oneSignal.handleNotificationReceived().subscribe(() => {
          console.log('Received Notification');
        this.oneSignal.handleNotificationOpened().subscribe(() => {
          console.log('Opened Notification');
        this.oneSignal.getIds().then(data => {

Thanks everyone.

Maybe there is an test app from one signal that you could try to find out if it’s the plugin or one signal in general that’s not working… :thinking:

Does push work in any other app on this device?

Thanks for reply. In another app, push work in this device.

Thanks for reply. Nope, it’s not an test app. Event I updated at latest cordova one signal plugin, that still not work.

this is my struggling
