The popular social media app went dark for millions of users Saturday night. The Chinese-owned app has been banned by federal officials.

TikTok said it will be forced to go dark on January 19, the day the ban is set to take effect, without more assurances it won't be enforced.

Users were unable to access TikTok Saturday, instead seeing a pop-up message on their screens saying "a law banning TikTok has been enacted."

TikTok may get a 90-day extension to save it from its imminent ban if President-Elect Donald Trump decides so.

TikTok said it will go dark Sunday without assurances of "non-enforcement" of the law effectively banning the app.

A law that prohibits mobile app stores and internet hosting services from distributing the video-sharing platform to U.S. users takes effect on Sunday.
