Hello Holograph-4000-IOS,
Thank you for following up. We'd be happy to provide additional guidance.
To link a contact, you'll want to open the Contacts app. Tap on a contact. Tap "Edit" in the upper right-hand corner. Then, scroll to the bottom of the page. There, you'll see a "Link Contact" option. When you tap on "Link Contact," you'll be taken back to your list of contacts where you'll be able to select which contact you'd like to link.
Linking contacts is mainly used when you have created two separate contact cards or contact entries for one contact.
We hope that helps. Take care.
