Family sharing gives me no option for adding family members. IOS 16.3

Hey Littlenan,

Please try the steps below from this user guide:

Add a member to a Family Sharing group on iPhone

Add a family member with an Apple ID

The organizer of the Family Sharing group can add a family member who has their own Apple ID.

1. Go to Settings  > [your name] > Family Sharing, then tap  in the upper-right corner.

2. Tap Invite Others, then follow the onscreen instructions.

You can send the invitation using AirDrop, Messages, or Mail. If you’re near the family member, you can also tap Invite in Person and ask the family member to enter their Apple ID and password on your device

Let us know if this helps!

Best regards.
