Enatega Customer Application (App Language)

Is your feature request related to a problem? Please describe.
The application is asking for a specific language to select and when the user does that, the whole application gets reloaded.

Describe the solution you'd like
the application should be able to picked the language the system is already using and make it its default language.

No file or test is named in the issue. Start by locating the customer application's language selector and locale initialization, then check how the system language is detected and why selecting a language reloads the application. Done means the app uses the system language by default and selecting or applying it does not trigger an unnecessary full reload.
