Why can't I share iPhone location?

if you're experiencing issues with sharing your location on your iPhone 11 Pro Max running iOS 16, you might want to try the following steps to troubleshoot the problem:

1. Make sure that Location Services are enabled on your iPhone and for the specific apps that you're trying to share your location with. You can do this by going to Settings > Privacy & Security > Location Services and ensuring that it's turned on. Scroll down to see a list of apps and make sure that the relevant app is set to "While Using the App" or "Always," depending on your preference.
2. If you're trying to share your location through a specific app, make sure that the app has permission to access your location. You can do this by going to Settings > Privacy & Security > Location Services and selecting the app in question. Choose the appropriate location access setting.
3. Resetting your location and privacy settings can help resolve issues. To do this, go to Settings > General > Transfer & Reset > Reset > Reset Location & Privacy. Keep in mind that this will reset all location and privacy settings, so you'll need to go through them again after the reset.
4. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it.
   2. Still not solved --> Force restart iPhone - Apple Support
5. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
   1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
6. Make sure you have the latest updates installed.
   1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
   2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.
