I was studying the construction of the checkout_index_index file on the checkout page, and I realized that there is no way to move an element using the "move element". But it is possible to order an order in which it appears using ordering. However, when I use sort order to move some elements. Payment methods disappear. Then I ask, How is it used correctly? can I place a sort order anywhere inside the "item"? should I put where?.
<item name="sortOrder" xsi:type="string">0</item>
