title: i18next dealing with multiple translation files nested namespaces
body: <p>I'm having issues figuring out how to lazy load my translations with i18next.</p>
  <p>Here's my setup:</p>
  <pre><code>i18n
    .use(Backend)
    .use(LanguageDetector)
    .use(initReactI18next)
    .init({
      debug: NODE_ENV === 'development',
      defaultNS: 'translation',
      fallbackLng: false,
      fallbackNS: 'translation',
      keySeparator: false,
      lng: 'en',
      load: 'currentOnly',
      nsSeparator: '.'
    });
  </code></pre>
  <p>I have a folder structure like this:</p>
  <pre><code>├── src
  │   └── pages
  │       ├── customer
  │       │   └── home.tsx
  │       └── manager
  │           └── dashboard.tsx
  </code></pre>
  <p>I keep my translations in <code>/public/locales/en/translation.json</code> and this works fine. However, my app is expanding and I don't want to keep all my translations for a language in single file. E.g. the <code>customer</code> doesn't need to download all the translations for things happening on the <code>manager</code> portal.</p>
  <p>My goal is to download translations specifically for the manager's Dashboard.</p>
  <p>I've tried creating a file and adding it to this location</p>
  <blockquote>
  <p><code>/public/locales/en/manager/dashboard</code></p>
  </blockquote>
  <p>And then in my React component I make use of the following hook:</p>
  <pre><code>...
    // This probably needs to change
    const { t } = useTranslation('manager.dashboard');
  
    return &lt;div&gt;{t('Hello World')}&lt;/div&gt;
  </code></pre>
  <p>And just to test it out my <code>/public/locales/en/manager/dashboard.json</code> (I really want to maintain this file structure) file has a single key value in it:</p>
  <pre><code>{ &quot;Hello World&quot;: &quot;Goodbye World&quot; }
  </code></pre>
  <p>It's not working (works if I add this key to the <code>/public/locales/en/translation.json</code> file)</p>
  <p>How can I change my configuration to get this organized nest translation file structure to work.</p>
