The company said TikTok was coming back online in the U.S. after President-elect Donald Trump provided assurances to its service providers.

TikTok restored service to users in the United States on Sunday just hours after the popular video-sharing platform went dark in response to a federal ban, which President-elect Donald Trump said he would try to pause by executive order on his first day in office.

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.

The Supreme Court has unanimously upheld the federal law banning TikTok beginning Sunday unless it’s sold by its China-based parent company.
