Problem Description

So as per the code for the Switch Component
react-native-windows/packages/@react-native-windows/tester/src/js/examples-win/Switch/SwitchExample.windows.js at main · microsoft/react-native-windows

there are four toggle button .

The first button (1,1) doesn't have liveregion prop
Second one (1,2) has liveregion prop set to none
Third one (2,1) has liveregion prop set to polite
Fourth one (2,2) has liveregion prop set to assertive

But when using narrator , all the buttons are behaving in the same way

Narrator.mp4

Steps To Reproduce

Run RNTester App ,Navigate to the switch component , and open the narrator app and try

Narrator should narrate 3rd and 4th button when its state changes multiple times.

Here's accessibilityLiveRegion.

Question is whether this is bugged behavior, not yet implemented, or behaving to spec with how focus works here.
@chiaramooney @Yajur-Grover Can you help identify where we are with live region?
