- Tap “Open ‘Accessibility’”.
- Further down, under “Downloaded apps”, tap “KidPair: breaks and schedules”. This is KidPair's own service, not a general phone setting.
- Turn the switch on and tap “Allow”.
If the row is grey or says “Access denied” / “Restricted setting”: Android sometimes restricts apps installed outside an app store this way. Open the app's page (KidPair has a button) → ⋮ at the top right → “Allow restricted settings”. Then turn the service on again.
