[Bug] Applying useApplyShippingAddressChange to a Saved Address Prevents Editing

Extensions

Hi @Liam-Shopify,

Thanks for the reply.

I did a simple test and managed to reproduce both the issue mentioned in the link and the one here. I posted my findings about the linked issue here: (REGRESSION) useApplyShippingAddressChange hook on one-page checkout changes back to the first saved address - #8 by macaron

In short, when the list of saved addresses is opened, the app changes the address. As a result:

  • If the address becomes invalid, the radio button is deselected (as described in this issue), but the input form does not appear. Also, the edit modal’s Submit button stops working.
  • If the address is valid, it behaves like the linked issue, where the input form for the default address appears.

It’s hard to say exactly how it should behave, but imo, as mentioned in the comment on that linked thread, I think it would be best if:

  • Changing the address via the app causes the radio button to become deselected.
  • Clicking on it brings up the address form, allowing the user to properly update their address.

I hope this is helpful as a reference.
