App developers had improper access to user data on Facebook

The video discusses how apps accessed user data from Facebook groups through admin authorization. Despite policy changes in April 2018 to restrict such access, apps could still access names and profile pictures of group members. Facebook required users to opt-in for data sharing, and later removed access for developers. The company found no evidence of data misuse. These changes followed the Cambridge Analytica scandal, where user data from 87 million Facebook users was accessed.
