Urgent Issue with Shipping Address on FULLY Site

I’m reaching out regarding an urgent issue on the FULLY site. When a customer tries to make a purchase, the Shipping Options used to appear automatically after entering their address. However, now it prompts “Add a Shipping Address” even when a correct address is entered, preventing the checkout from proceeding.

Could you please look into this as soon as possible? This is a time-sensitive matter, and we would appreciate a quick resolution.
