[Bug] Shopify cart permalink does not prefill address

But it seems that when shopper visit the link the first time, the address is already set in the backend. Just that the address fails to populate to UI.

Because

  1. The address is not prefilled when I first visit https://supplystore2021.myshopify.com/cart/50722249211926:1?checkout[shipping_address][city]=thisismyhometown
  2. Then in same browser tab, I visit https://supplystore2021.myshopify.com/checkout . Though this time the link has no param related to address, the address in checkout page is prefilled with city = thisismyhometown

@Liam-Shopify Would you be able to help us connecting to related dev? I think other merchants are facing the same issues too[1]. Thanks!

  1. Shipping Address cannot be prefilled in checkout
