Team admins can connect an address the team owns, such as links.example.com or example.com, to the Link-In-Bio List from Custom domain in its Settings. The page is the same as the Store's and websites' Custom domain page: it shows the DNS records to add, or adds them when Magpie hosts the domain's DNS, updates by itself as Magpie's checks find the records, and shows Live when the domain is ready.
Once the domain is live, visitors see the published list there, and the list's Magpie address opens the domain, so addresses already in social profiles keep working. Turn off Magpie address on the Custom domain page to show the list at both addresses. Address, QR code and Share in Settings, and the address the mobile app shares, use the domain.
A Magpie page block for a Store or website that has a live domain of its own now opens that domain.
