During tests with the platform and the cart system we found that the total amount is not reliable.
Many times we found that the total is not updated and it is completely wrong.
The worst part of this is that the amount usually tends to be bigger than the real total so it create rejection from users to continue with the shopping.
I don’t know if I am the only one affected with this issue but it should be a maximum priority to fix this as it just break completely the shopping funnel in many cases.
