Inviting someone to your family
Family invitations now explain, before you send them, what an invited relative can and cannot see. The invitation is a warm message of your own, sent through the system share sheet.
A relative who joins sees a first-step card. New arrivals from other family members reach you in at most one evening notification a day.
Step by step
Open Roots and choose to invite someone.
Read what they will and will not see, then write your own message.
Send it through the share sheet.
