TikTok, the popular Chinese-owned short-video app, has stopped working in the United States and disappeared from Apple and Google app stores. The sudden shutdown occurred on Saturday evening, just before a federal ban on the platform was set to take effect.

When users attempted to access the app, they were met with a pop-up message stating, “Sorry, TikTok isn’t available right now.” The message further explained, “A law banning TikTok has been enacted in the U.S. Unfortunately, that means you can’t use TikTok for now.”

In a surprising twist, the notice also mentioned that President-elect Donald Trump had indicated his willingness to work with TikTok to find a solution to reinstate the platform once he takes office. The company assured users to “stay tuned” for further updates.

Prior to the shutdown, TikTok had informed users that its service would be “temporarily unavailable” and that it was working to restore its U.S. service “as soon as possible.” However, the duration of the platform’s downtime remains uncertain.

The sudden disappearance of TikTok from US app stores has left many users wondering about the platform’s future in the country.
