Hi Igor
Thank you for coming back to us. Yes we have followed all of the steps in the documentation that you mentioned. Everything works apart from shipping not being billed if you don’t use the shipping calculator in the cart.
Anyway, so that we can test properly and work on a resolution we are currently cloning the site to create a staging server. It’s a very big site so will take a while to complete. I’ll message back here once we have everything ready and I’ll also paste our system status from staging too.
Kind regards
Darren
