language selection isn’t properly working in my apk.
couldn’t figure out why it happended or how to fix this issue

i did debug,, while this code(setLanguage) calls setLocale and sets the value that user selected, setLocale is being called again and overwritten by previous language. It gets called from LanguageHelper‘s this code

else {
            val lang = getPersistedData(context, Locale.getDefault().language)
        
            lang?.let { setLocale(context, lang) }

it passes en thro setLocale
wasted around 15 hours to solve this issue.. tried differenct metholds… still couldn’t

let me know if you need anything else

This is the code inside fragment

class SettingsFragment : BaseFragment() {
