If you can view a family member's live location and reports but not their speed and drive score, it may be due to permission settings. Your family member needs to grant you permission to view their speed and drive score.
This can be managed under the "Give Access" tab in their OtoZen app, where permissions to share speed and drive score data can be either granted or revoked by the family member.
Make sure your family member has enabled the necessary permissions for you to access this information.
