AmazonPay doesn't copy cart attributes and discounts

[niwa3]

We are using hydrogen and redirecting users to the online store's checkout page via the checkoutURL of the cart. 

URL likes: 'https://checkout.palmwork.jp/checkouts/cn/{ID}/information?discount=DISCOUNT'

But, in the checkout, if the user used AmazonPay, the checkout page is redirected and all of the cart attributes and discounts added by the storefront API are not copied.

Redirected URL: 'https://checkout.palmwork.jp/{shop id}/checkouts/{checkout id}?step=contact_information'

It has no problem with Shop Pay.

So, We think it is the problem of Amazon Pay.

Someone knows the solution or more information.

Any help with this is much appreciated.
