The iOS 27 family framework completely redesigned parental controls. If all family devices haven't refreshed their status, the sync will break.
- On your iPhone, open Settings > Family.
- Look to see if there is a "Get Started" prompt near the top to review and migrate existing parental controls. If it's there, complete that flow first.
Step 2: Force-Reset the Contact Token Loop
To fix the underlying glitch, you need to trick the watch into re-authorizing your right to manage its contacts. Keep your child's Apple Watch nearby, unlocked, and charged for this step.
- On your iPhone, go to Settings > Family > [Child’s Name] > Screen Time > Communication Limits
- Change both During Screen Time and During Downtime temporarily to Everyone. (This opens a temporary window so the watch stops blocking messages right away).
- On that same page, locate the Manage [Child's Name] Contacts switch. Toggle it OFF.
- Wait about 30 seconds, then toggle Manage [Child's Name] Contacts back ON.
- Check the child's Apple Watch immediately: A notification or a pop-up should appear on the watch face asking the child to approve the parent's request to manage their contacts.
- Tap Approve on the watch face
