Hello,
Move to Shopping Cart doesn't reflect at a time while click on Move to Shopping Cart link. It reflect when we click Update Changes button.
To reproduce this issue
- Login into magento2 admin panel.
- Click on Sales > Orders
- Click on Create New Order
- Select Appropriate customer & store view
- Click on Add Products & Select Appropriate product
- Go to Action header and select Move to Shopping Cart option & click on Update Items and Quantities.
- After completion of AJAX request added product doesn't reflect on shopping cart on left side from Shopping Cart block.

This is the bug because when we add to shopping cart product it reflect at a time on left side block of shopping cart.
When we click on Update Changes button from left block[At the end] , Product display in shopping cart block, So there must ajax render issue.
