I have tried it on several occasions, I have cleared the cache and I have tried it with various internet browsers and none of it works.
If you want, I can provide access and a means of provisional payment so that you can test the system for yourself, and see what is happening.
I see two errors:
1.- Orders are not automatically updated and the selected sound does not sound.
Orders are only updated when I reload the page.
2.- I am using the woocommerce shipping system, with three modes, free shipping when the order is greater than a quantity, the shipping cost for orders of a lower amount and the collection at the establishment.
The chosen option is not saved in the purchase order.
