The staging site is up, you can use the same login information at the link in private content.
The issue started to happen right after I updated the theme to 7.6.0. Since then I have updated as many plugins as possible (due to license issues some I am not able to update some of them). The issue is still there.
To replicate:
1) Start adding products to the cart – you can do that from the homepage
2) Check the cart subtotal in the right top corner after each product
3) Usually the issue happens after few products are added
4) You can go to the cart after few products – sometimes the products disappear this way
5) If the issue does not happen, try to empty the cart and start again – the issue happens 80 % of time
Thank you!
