The main reasons why location sharing may not work on an iPhone include:
- Location Services being turned off in Settings > Privacy & Security.
- The app you are using not having permission to access your location.
- Network connection problems (Wi-Fi or cellular data).
- Privacy restrictions set in Screen Time or Content & Privacy Restrictions.
- Outdated iOS software causing glitches.
- Settings in the Find My app not allowing location sharing.
To fix this, ensure Location Services are enabled, the appropriate app has location permissions (e.g., set to "While Using" or "Always"), and that you have a stable internet connection. Also, check that "Share My Location" is enabled under your Apple ID in Find My. Restarting your iPhone or updating to the latest iOS version can also help resolve software-related issues. If Screen Time or privacy restrictions are enabled, verify that they are not blocking location sharing.
