Answer 1

Never used it but looking at the source code it says you need to use the languages option as an array of language codes. More specific patterns should come first, e.g. 'en_us' before 'en'. This can also contain mapping of <url_value> => <language>, e.g. 'english' => 'en'.

ou need to change the option to 'languages' => ['en_us'],

Answer 2

You must setup language for app config.

UPD: Setup config(frontend/config/main.php) to needed language for app. Then first time app will launch in this language: 'language' => 'en'.

If this not work check in incognito mode, you must clean old session saved cookies
