Hello aaangellike,
If you're not seeing the People tab in the Find My app, that could be based on which country you're located in. As mentioned in Share your location with your family, "Location sharing isn't supported in South Korea and might be unavailable in other regions due to local laws." Even if you aren't actually located in one of those countries, it might still affect you if your iPhone was originally purchased from one of those countries.
If you're located in a country that does support location sharing, and your device was purchased in a country that supports it, try out these steps:
- Restart your iPhone: Restart your iPhone.
- Update to iOS 13.3 if you aren't already running that version: Update your iPhone, iPad, or iPod touch.
- Go to Settings > Screen Time > Content & Privacy Restrictions. If this is enabled, make sure Location Services is set to Allow.
- Go to Settings > Privacy > Location Services, and make sure it's enabled there.
- See if you're able to locate your friends by logging into iCloud.
If the issue continues, we recommend that you reach out to Apple Support for more help: Get Support
Thanks.
