The EU on Monday launched a probe into TikTok's spinoff Lite app and threatened to suspend an "addictive" feature on it that rewards users for watching and liking videos, amid child-safety concerns. TikTok Lite users can win rewards if they log in daily for 10 days, if they spend time watching videos (with an upper limit of 60 to 85 minutes per day) and if they undertake certain actions, such as liking videos and following content creators.
