Currently, when leaving the checkout page to change items or do whatever, the customers' information is not saved and has to be reentered.

So for example, if the customer selected a wrong item or a wrong number of items and uses the "edit cart" button and then returns to the cart, they have to enter their information again.

Can you please change the form to be sticky - i. e once the data was entered for it to re-appear when the customer goes back to the checkout page.
