PIP doesn't work on iOS or Android

**Describe the bug**
PIP doesn't work for me on iOS or Android - it does nothing at all on both.

**To reproduce**
```
const ref = useRef(null);

// then add a button that calls this
ref.current?.togglePip();
```

I have updated AndroidManifest with:
```
android:resizeableActivity="true"
android:supportsPictureInPicture="true"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density|smallestScreenSize|orientation"
```

and checked this in XCode:

**Expected behavior**
Video should go into picture-in-picture mode, but instead nothing happens. Should it just work?
