Why doesn't Woocommerce see the ACF code?

Question

WordPress

Childish question: Why Woocommerce doesn't see ACF plugin code (custom fields)?
The code is in the footer. On the main page - it is displayed, on the Maganin page - no. Can you shed some light on this point? And how can it be solved (preferably taking into account ACF)?
For example, I took the code of a regular link

<a href="mailto:<?php the_field('email') ?>" class="mail">
  <span><?php the_field('email') ?></span>
</a>

In the browser (Shop page) shows the following code:

<a href="mailto" class="mail">
  <span></span>
</a>

Answer 1

See cycle. I suspect that it the_field($field_name, $post_id);does not receive id

Answer 2

Ivan, alas, your option does not work, the result is the same

Answer 3

Most likely, wp_query was called before your ACF and you did not reset it
