Instagram rolled out a new Map feature that lets users see their friends' locations in real time. Here's why privacy experts are concerned.

Some 170 million people got access to Instagram's new location-sharing feature, so why is the Map so empty? In the app's loneliest corners, Meta and its users may be fighting a quiet battle.

The service rolled out this week, prompting confusion and safety concerns. Meta, which owns Instagram, said the feature was turned off unless users activated it.
