[Bug]: Duplicate subscription after closing and opening the app again

[qidulak]

What happened?

Not sure, if this is bug, but when I start freshly installed ap on device and log user in, it will properly create subscription. But when I kill the app and start again, I see in one signal dashboard duplicated subsription, for different OneSignalID and with sstatus not PermissionNotGranted. This subscription is also without external Id filled.

After another app kill and start nothing change and this subscription just hang in the dashboard. I can normally send Push notifications to user 28509928-339b-acb7-e601-84f616f2e0e0.

Did not noticed this behavior for iOS devices/simulators

this is how I init/login user

  oneSignalInit(appId: string): Observable<boolean> {
    // Uncomment to set OneSignal device logging
    // 0 = None, 1 = Fatal, 2 = Errors, 3 = Warnings, 4 = Info, 5 = Debug, 6 = Verbose
    OneSignal.Debug.setLogLevel(6);
    OneSignal.Debug.setAlertLevel(0);

    OneSignal.initialize(appId);

    OneSignal.Notifications.removeEventListener('click', this.clickHandler);
    OneSignal.Notifications.addEventListener('click', this.clickHandler);

    OneSignal.Notifications.removeEventListener(
      'foregroundWillDisplay',
      this.foregroundDisplayHandler,
    );

    OneSignal.Notifications.addEventListener(
      'foregroundWillDisplay',
      this.foregroundDisplayHandler,
    );


    return from(OneSignal.Notifications.getPermissionAsync()).pipe(
      switchMap((hasPermission) => {
        if (hasPermission) {
          return of(true);
        } else {
          return from(OneSignal.Notifications.requestPermission(true));
        }
      }),
    );
  }
  
  userChangedListener = (event: UserChangedState) => {
    if (event.current.onesignalId) {
      OneSignal.User.pushSubscription.optIn();
      this.notificationIdSubject.next(event.current.onesignalId);
    }
  };

  // When login, we collect oneSignal ID for user
  login(userName: string): Observable<string> {
    OneSignal.User.addEventListener('change', this.userChangedListener);
    OneSignal.login(userName);

    return from(OneSignal.User.pushSubscription.getIdAsync()).pipe(
      switchMap(() => this.notificationIdSubject.asObservable()),
    );
}

Steps to reproduce?

1. Launch the app and let perorm init and login 
2. Kill The app
3. Launch the app again

What did you expect to happen?

I suppose there not should be another subscription

Hi @qidulak, thanks for reporting this. It is a bug in the SDK that is fixed in #2099.

It has no adverse side effects except creating a pointless user + subscription instance.
