Thank you for the contribution.
I see that when you add a product ot the cart, and go the the cart page. The cart page does not reflect any changes.
Can you please test it at your end ?

Is the WooCommerce installation local or remote?

I found out that if I use Xampp, the update takes a minute or two, but is really fast on an online installation.

I recommend that you experiment with a different WooCommerce installation and see if that may be the reason.

I had tested it online as well. Can you try deploying your branch on netlify or vercel and test it once.
Could you also raise a fresh PR please, as there had been changes after hat ?
