At a glance
- Where: Settings → Family → Subscriptions → iCloud+
- Changes: Shared subscription capacity for separate Apple Accounts
- Limits: A shared login, Shared Album or Shared Photo Library creates a different access arrangement and needs its own review.
Steps
- Confirm each person uses their own Apple Account.
- Review the shared subscription independently of any photo-sharing features.
- Inspect Shared Albums and Shared Library participants if the concern is who can see a specific photo.
Check the result
Trace a harmless sample through the exact account and library view in question. A thumbnail on another device is a reason to check the sharing path, not proof that every Family Sharing member sees your library.
