In our shop (British columbia), we have GST and PST.
In Order Printer, the following code:
<td>
{% for tax_line in line_item.tax_lines %}
{{ tax_line.title }} {{ tax_line.price | money }} <br/>
{% endfor %}
</td>
does not work when I use Shopify POS and Shopify Payments in test mode. Whenever there is one product with GST only in the order, no line_item has a valid variable line_item.tax_lines.
In my order I have several products with GST and PST and only one product with GST only.
