Can't focus into text fields, Android + external keyboard

In the first Expo example on https://reactnative.dev/docs/textinput - with an external physical keyboard on Android, we don't seem to be able to move the focus into/ between these input fields. It's fine if you tap the screen, and it's fine if Talkback is on and we alt+arrow between the fields. But with Talkback off, and just using the keyboard, we can't get focus into the fields.

Expected Results

That the fields can be focussed by the keyboard

リンクされている Snack と React Native ドキュメントの最初の TextInput の例から始め、外付けキーボードを接続し、TalkBack を無効にした Android で問題を再現します。キーボードナビゲーションで画面をタップせずにテキストフィールド内およびテキストフィールド間にフォーカスを移動できれば完了です。
