Hi @tepid kernel there's iOS native API called STPLocalizationUtils.overrideLanguage that allows you to override the language, but it's not surfaced in react-native SDK. You might want to build your own bridge to call it in your application
Thanks @carmine ledge will do that eventually.
For now, as a temp workaround, it is possible to configure the xcode project to only use one locale by setting the info plist key CFBundleLocalizations
