By Dietrich KnauthNEW YORK, Aug 3 (Reuters) - TikTok has agreed to settle three lawsuits brought by young people who accuse social media companies of designing their platforms to be ‌addictive and harming their mental health, a plaintiffs' lawyer said Monday. The terms of the ‌settlements are confidential and subject to the finalization of written settlement agreements with TikTok, according to Joseph VanZandt, a lawyer for ​the plaintiffs. The plaintiffs' claims against Meta Platforms, Google's YouTube and Snap Inc's Snapchat will continue. Another 2,600 cases making ​similar claims, brought by individuals, school ‌districts, municipalities and states, are pending in California federal court. In addition, nearly every ​state attorney general has sued social media companies in their own state courts.
