onUpdate is running but not updating the Widget graphically

Question

I currently have the most basic widget possible for attempting to force an update on a button press, a single button which updates its own label from "old text" to "new text".

This has worked exactly once, and then never again. According to the logs it should be working. All I want, is a consistent way to update my widget on a button press.

This is the entirety of the code aside from an empty main activity and XML files.

public class ExampleAppWidgetProvider extends AppWidgetProvider {
    private static final String MyOnClick = "myOnClickTag";
    private static final String REFRESH_ACTION = "refresh";
    String globalString = "Blank";
    static boolean globalBoolean = false;

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        for (int appWidgetId : appWidgetIds) {

            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.example_widget);
            views.setOnClickPendingIntent(R.id.example_widget_button, getPendingSelfIntent(context, MyOnClick, appWidgetIds));

            if(globalBoolean == true) {
                views.setCharSequence(R.id.example_widget_button, "setText", "new text");
                Log.w("Widget", "displaying new text");
            }else{
                views.setCharSequence(R.id.example_widget_button, "setText", "old text");
                Log.w("Widget", "displaying old text");
            }

            appWidgetManager.updateAppWidget(appWidgetId, views);
        }
        super.onUpdate(context, appWidgetManager, appWidgetIds);
    }

    protected PendingIntent getPendingSelfIntent(Context context, String action, int[] appWidgetIds) {
        Intent intent = new Intent(context, getClass());
        intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);
        intent.setAction(action);
        return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_MUTABLE);
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        super.onReceive(context, intent);//add this line
        if (MyOnClick.equals(intent.getAction())) {
            globalString = "new text";
            globalBoolean = !globalBoolean;

            Bundle extras = intent.getExtras();
            if(extras != null) {
                int[] appWidgetIds = extras.getIntArray(AppWidgetManager.EXTRA_APPWIDGET_IDS);
                if (appWidgetIds != null && appWidgetIds.length > 0) {
                    Log.w("Widget", "Calling onUpdate()");
                    this.onUpdate(context, AppWidgetManager.getInstance(context), appWidgetIds);
                }
            }
        }
    }
}

When I press the button I can see from the logs that it does enter onUpdate() and it even goes into the correct part of the if statement:

2023-01-18 21:08:16.900 17447-17447/com.example.widget_test_2 W/Widget: Calling onUpdate() 2023-01-18 21:08:16.901 17447-17447/com.example.widget_test_2 W/Widget: displaying new text

And yet, the widget does not graphically update.

I think that what I saw originally might have been a fluke. While learning to make widgets I followed Coding In Flows widget tutorial which is now 5 years old, and it only updates graphically once per hour despite also forcing an update on click (a lot of that tutorial doesnt work anymore). I think in 2023 I must need to do something else in order to force this update to work consistently, but the majority of the posts I can find on this subject are pretty old, or I've attempted, or don't answer my question.

Can someone please provide a code example of what I need to change to force an update?

Thanks!
