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.

Start by locating the customer application's language selection and initialization entry points, then trace what happens when a language is chosen and the application reloads. Done means the app detects the system language, uses it as the default, and avoids requiring a separate language selection.
