suggestion: Spinner width may need to be set to 0dp for chain weights to apply.

The spinner has a horizontal weight assigned, yet its width is set to wrap_content. In a ConstraintLayout chain with weighted distribution, each view that participates should use a 0dp width. Consider revising the spinner’s width to 0dp to ensure its weight is honored as intended.

Suggested implementation:

    <Spinner
        android:id="@+id/time_interval_spinner"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:layout_constraintHorizontal_weight="1"
        ... />

Ensure that the Spinner element has its associated constraints in the ConstraintLayout chain correctly set so that the 0dp width together with the assigned weight produces the desired layout.
If your spinner is defined elsewhere or uses a different id or attributes, adjust the id/attributes accordingly.
