To create a Connection between two people, who each have their own charm, each person would need to pair their charm to their own device.
The order we recommend you follow is:
1. Person A creates an account by tapping "I Have a Charm" in the app
2. Person A invites Person B to connect by tapping "Invite A Loved One" in their Settings
3. Person B creates an account by accepting the invitation
4. Person B clicks "Add Charm" in their Connection with Person A to pair their charm
