Makers can add and assign multiple addresses. For instance, if your business address is XX but your product is shipping from YY, you'll need to add additional addresses.
Under the PROFILE section of your LibDib account, click on Addresses on the left hand side. The address used during onboarding is set as your default address. To change this, click ADD ADDRESS below the box and enter the new address. Then, once you've added it, you can assign it as needed.
