Angular translation service subscription in lazy loaded module

Question

I have imported TranslateModule in app.module.ts:

export function createTranslateLoader(http: HttpClient) {
  return new TranslateHttpLoader(http, './assets/i18n/', '.json');
}

imports: [...
 TranslateModule.forRoot({
      loader: {
        provide: TranslateLoader,
        useFactory: createTranslateLoader,
        deps: [HttpClient],
      },
    }),
]

And then in the app.component.ts:

  ngOnInit(): void {
    this.translateService.setDefaultLang('sl');
    this.translateService.addLangs(['en', 'sl', 'hr']);

    this.selectedLanguage = localStorage.getItem(AppSettings.LS_LANGUAGE)!;

    if (!this.selectedLanguage) this.setLanguage('sl');
    else this.applyLanguage();
  }

I change the language with the setLanguage function

  public setLanguage(lang: string): void {
    localStorage.setItem(AppSettings.LS_LANGUAGE, lang);
    this.selectedLanguage = lang;
    this.applyLanguage();
  }

 private applyLanguage() {
    this.translateService.use(this.selectedLanguage);
  }

In the lazy loaded module, I import the TranslateModule as such:

imports: [..., TranslateModule.forChild()]

But when I subscribe to a translation in the lazy loaded module, it only translates it initially, but doesn't update, when I change the language:

this.translateService
      .get('...')
      .subscribe((translation) => console.log(translation));

If I move the function above, to app.module.ts, it works fine, but once I move it to the lazy loaded module, it no longer works.
