Android app does not support languages that are not in the android system for per-app languages

Question

I have a problem, my application does not support languages that are not in the android system. When I test the APK everything is fine, but after releasing to play store I have a problem. I am trying to change languages programmatically.

val appLocale: LocaleListCompat = LocaleListCompat.forLanguageTags(languageCode) AppCompatDelegate.setApplicationLocales(appLocale)

I used the article https://developer.android.com/guide/topics/resources/app-languages

Edit

I resolved this problem added this:

android {
bundle {
    language {
        enableSplit = false
    }
}}
