TikTok said on Sunday it would resume service to U.S. users after being blocked the night before.

TikTok said in a statement that its video platform would be back online after President-elect Donald Trump provided necessary assurances to the company's service providers.

TikTok said in a post on They face no penalties for providing TikTok services, which serve more than 170 million Americans and allow more than 7 million small businesses to thrive. "

"This is a strong stance for the First Amendment and against arbitrary censorship. We will work with President Trump on long-term solutions to keep TikTok in the United States," the company added.

Just hours before withdrawing TikTok, Trump posted on Truth Social calling for the app to remain available.

Trump said in the post that he wanted the video to be played so that his inauguration on Monday would be broadcast.

"I will issue an executive order on Monday extending the time the legal ban is in effect so that we can reach agreements to protect our national security. The order will also confirm that any companies that helped prevent TikTok from shutting down prior to my order will not will bear any responsibility."

As of early afternoon, TikTok still had limited availability and the platform's content could be accessed through a web browser.

The law banning TikTok was scheduled to take effect on Sunday, allowing the president to extend the ban by 90 days if certain conditions are met.

Under a law signed by President Joe Biden in April, TikTok would be banned unless its Chinese owner ByteDance sells the company to a non-Chinese buyer.

Ahead of the ban, both Biden and the incoming Trump administration appeared to be reversing their previous stance on TikTok.

Trump, who advocated for a ban during his first term as president, came out in support of TikTok during the campaign and said he would save the app.

After the Supreme Court approved the law on Friday, the Biden administration issued a statement saying it would not enforce the ban, leaving that responsibility to Trump.

But TikTok said those assurances were not enough to prevent the app from being removed from the App Store and suspended service to U.S. users on Saturday night.
