WooCommerce COD FEE not applied

Hi,
for some reason, the additional fees for “Cash on Delivery” are not being displayed (or applied).
I have tried using both a plugin (WooCommerce Smart COD) and custom code in the “functions.php” file (using the code suggested here: https://www.minimamente.com/sovrapprezzo-per-pagamento-alla-consegna/) in the child theme, but it’s not working.
Do you have any suggestions?

I look forward to your guidance.
Regards
