TikTok, the Chinese tech company, ByteDance-owned social media platform is no longer available in the United States. The application and the company that runs it have warned its users in the country that the application may no longer be available from Sunday after the US Congress passed legislation banning the application.

Apple and Google removed TikTok from their app stores Saturday, complying with a law requiring China's ByteDance to divest the social app or see it face an effective ban in the U.S.

A looming ban on TikTok set to take effect on Sunday presents a multibillion-dollar headache for app store operators Apple and Google.

TikTok stopped working in the United States late on Saturday and disappeared from Apple and Google app stores ahead of a law that takes effect Sunday requiring the shutdown of the app used by 170 million Americans.

TikTok, owned by ByteDance, is on the verge of being banned in the United States. The thing is, the government could go after other ByteDance apps, and there are quite a few of them operating in the U.

The Chinese-owned company said it would cut off its services unless the U.S. assures Apple, Google and other companies that they would not be punished for hosting and distributing TikTok.

While TikTok remains hugely popular in Brazil, Indonesia and other markets, its 170 million users in the United States are its most valuable.

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

With President-elect Trump adding uncertainty around whether a TikTok ban will go into effect, the focus is now turning to companies like Google and Apple

TikTok is set to be banned tomorrow. Here's what time the ban could start in the U.S. and what the app could look like for users trying to access it on Sunday.

The app had more than 170 million monthly users in the U.S. The black-out is the result of a law forcing the service offline unless it sheds its ties to ByteDance, its China-based parent company.
