Currency Suffix on Cart/Checkout Pages

function addPriceSuffix($format, $currency_pos) {
	switch ( $currency_pos ) {
		case 'left' :
			$currency = get_woocommerce_currency();
			$format = '%1$s%2$s ' . $currency;
		break;
	}
	
	return $format;
}

function addPriceSuffixAction() {
	add_action('woocommerce_price_format', 'addPriceSuffix', 1, 2);
}

add_action('woocommerce_before_cart', 'addPriceSuffixAction');
add_action('woocommerce_review_order_before_order_total', 'addPriceSuffixAction');

I have used the above code to add USD to the cart and checkout pages on my site. I think the latest WC update broke this code.

How would I edit this code to have the USD suffix appear again on my cart and checkout pages only (it gets a little long/cluttered on catalog and product pages).

Thanks in advance and have a great day.
