the behavior subject remains static and does not update

Working on setting my language in the BehaviorSubject with a default value using a LanguageService. The service structure is as follows

import {Injectable} from '@angular/core';
import * as globals from '../../../environments/globals';
import {BehaviorSubject} from 'rxjs';

@Injectable()
export class LanguageService {
    languages = globals.languages;

    language = new BehaviorSubject<string>(this.languages.polish.code);

    setLanguage(code: string) {
        console.log(code)
        this.language.next(code);
    }

    getLanguage() {
        return this.language.asObservable();
    }
}

This is provided by the SharedModule and imported into every single component I have. While using setLanguage, I can see the correct code being set. However, when I call getLanguage, it always returns me the default value. This has not been an issue with BehaviorSubject before, so I am unsure of the cause.

I have implemented

this.languageSubscription = this.languageService.getLanguage().subscribe((language: string) => {
            console.log(language);
        })

in one of my components to test, but unfortunately, it is not working. Any suggestions?

I suspect the problem is related to routing. When I switched to AsyncSubject or normal Subject, on changing screens, getLanguage() does not return anything as if it's never called.

eliminate service from all providers arrays and update decorator to:

@Injectable({providedIn: 'root'})
