Short Answer 
To enable location sharing, ensure Location Services are active on both devices and check that permissions are properly set within the Find My app or Messages. Additionally, both devices need an internet connection, and any time limits on location sharing should be reviewed, along with restarting devices and checking for software updates to troubleshoot any issues.
Step 1: Verify Location Services
Ensure that Location Services are enabled on both devices. The person sharing their location should navigate to Settings > Privacy > Location Services and make sure it is turned on. This is crucial as disabling this feature will prevent any location sharing.
- Go to Settings
- Select Privacy
- Access Location Services
- Turn on Location Services if it is off
Step 2: Check Permissions and Connectivity
Confirm that the permissions to share location are intact. The sharer must check in the Find My app or Messages to ensure that permission has not been revoked. Additionally, both devices must have an active internet connection as connectivity issues can hinder location sharing.
- Open Find My app or Messages
- Verify permission settings for location sharing
- Ensure both devices have active internet connections
Step 3: Troubleshoot for Time Limits and Software Issues
Consider whether the location sharing was set for a limited time. If it has expired, they should extend the sharing period. Additionally, if there are software glitches, restarting both devices can often resolve the issue, or checking for updates on any app being used can help ensure smooth functionality.
- Check if location sharing has a time limit
- Restart both iPhones
- Look for app updates or reinstall if problems persist
