Hi Izabela,
Here are a few steps to fix your ACF custom fields issue on products:
Location Rules: Ensure the field group’s location rule is set to “Post Type” is equal to “Product”.
Display Rules: Make sure there are no extra rules hiding the fields.
Theme Compatibility: Try switching to a default theme to see if that helps.
Plugin Conflicts: Deactivate other plugins to check for conflicts.
Updates: Ensure ACF and WooCommerce are up-to-date.
Screen Options: On the product edit page, check that custom fields are enabled in “Screen Options” at the top right.
