TikTok warned it US users late Saturday that its platform would be "temporarily unavailable" beginning Sunday Jan. 19, to comply with a federal law that effectively bans the app in the US.
"We regret that a U.S. law banning TikTok will take effect on January 19 and force us to make our services temporarily unavailable," TikTok's message to users read.
"We're working to restore our service in the U.S. as soon as possible, and we appreciate your support. Please stay tuned."
In an interview with NBC on Saturday, president-elect Donald Trump said he would likely grant TikTok a 90-day extension to work out a deal with the government and keep the app up and running.
