Z Fold 7 pre-order delivery address

Hello,

My partner and I preordered Samsung Galaxy Z Fold 7 on 20.07, thinking that the phones will get delivered this week. But, taking into account all the uncertainty related to the delivery dates, it seems it will take time until they get shipped and delivered.

The problem is that next Friday (08.08) we are moving into a new apartment and we will need to change the delivery address for the phones, if they are not delivered by then.
So, I would like to know what to do in case we need the phones delivered to the new home address, as changing the delivery address for the orders is not possible in the app or the web portal?

Thanks
