I want to add static text above the price. I tried to add as explained in the thread (Magento 2: How to add text within container via XML) but it didn't work for me.
<referenceContainer name="product.info.main">
<block class="Magento\Catalog\Pricing\Render" name="product.price.final" before="product.price.tier">
<arguments>
<argument translate="true" name="text" xsi:type="string">Mytext</argument>
<argument name="price_render" xsi:type="string">product.price.render.default</argument>
<argument name="price_type_code" xsi:type="string">final_price</argument>
<argument name="zone" xsi:type="string">item_view</argument>
</arguments>
</block>
</referenceContainer>
<action>
tag ?
