The Supreme Court upheld a law banning TikTok in the US over national security concerns unless its Chinese parent ByteDance sells it. Without immediate assurances from the Biden administration, the app will go dark on January 19.

TikTok warned it will go dark in the United States unless President Joe Biden's administration provides assurances to companies like Apple and Google that it will not face enforcement actions when a ban takes effect.

The app’s availability in the U.S. has been thrown into jeopardy over data privacy and national security concerns.
