Language Persistence Issue in Enatega Multivendor Customer App

Describe the bug
Upon changing the language in the Enatega Multivendor Customer App, the selected language does not persist after closing and reopening the app. While the language setting in the app's settings menu reflects the new selection, the actual displayed language remains the same as before the change.

To Reproduce
Steps to reproduce the behavior:

Open the Enatega Multivendor Customer App.
Navigate to the app settings.
Change the app language to a different one.
Close the app.
Reopen the app.
Expected behavior
The app should retain the selected language even after closing and reopening. The displayed language should match the newly chosen language setting in the app.

Reproduce the language change and restart flow on iOS, then trace how the Customer App settings stores and reloads the selected language. Done means the chosen language is still displayed after closing and reopening the app; no file or test location is identified in the issue.
