Wear OS Layout Issue: Only Upper Left Quadrant Usable on Samsung Galaxy Watch 4

Question

I'm developing a Wear OS toy app for a Samsung Galaxy Watch 4. Despite what I believe to be correct configurations (i.e. no errors in app building or deploying - except for the "glitch" I will mention here), my app's layout only occupies the upper left quadrant of the screen, with the rest of the screen remaining black. Other apps on the watch use the full screen without issues.

I've verified my layout and manifest XML files, and they appear to be correct. The problem persists regardless of the layout structure I use.

Has anyone experienced similar issues or have suggestions on how to resolve this? here is an example of my activity_layout.xml

<?xml version="1.0" encoding="utf-8"?>

        <androidx.constraintlayout.widget.ConstraintLayout

            <Button
                android:id="@+id/button2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginStart="33dp"
                android:layout_marginTop="4dp"
                android:layout_marginEnd="30dp"
                android:onClick="reset"
                android:text="Reset"
                app:layout_constraintEnd_toEndOf="parent"
                app:layout_constraintStart_toStartOf="parent"
                app:layout_constraintTop_toTopOf="parent" />

            <TextView
                android:id="@+id/textView"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginStart="50dp"
                android:layout_marginTop="12dp"
                android:layout_marginEnd="46dp"
                android:layout_marginBottom="8dp"
                android:text="0"
                android:textSize="20sp"
               app:layout_constraintEnd_toEndOf="parent"
               app:layout_constraintStart_toStartOf="parent"
               app:layout_constraintTop_toBottomOf="@+id/button2" />
        </androidx.constraintlayout.widget.ConstraintLayout>
    </FrameLayout>
</androidx.wear.widget.BoxInsetLayout>

I expect the view to occupy all the watch screen
