TikTok's app effectively shut down in the US, just hours before a law banning the popular video-sharing platform was set to go into effect. The app was shut down on Saturday, displaying a message that the app "isn't available right now," but expects resolution under President-elect Trump. The Supreme Court on Friday unanimously upheld the divest-or-ban law, which gave TikTok's China-based parent company ByteDance until Sunday to divest from the app. President Trump said Saturday that he would most likely give TikTok a 90-day extension. Following Friday's Supreme Court decision, TikTok CEO Shou Zi Chew thanked the president-elect for his commitment to finding a solution to keep the app accessible in the US.
