Hello @ksenia-zlotin,

Thanks for the report and collaboration!

We have tried to reproduce the issue in the latest development branch 2.4-develop, and the issue seems reproducible for us. Please have a look at the below screenshots for reference:

1. Here in the below screenshot, first we have created and selected the new shipping address and then back to the Shipping address and select the default shipping address, and pressed the "Next" button, after that if try to access the cart page the address variable contains the new shipping address:

2. In the below screenshot, you can see we have selected the default shipping address:

But we can place the order successfully with the selected shipping address, so please let us know the use case where you are facing an issue with the current flow.

Thanks
