TikTok is resuming services to its 170 million users in US after President-elect Donald Trump said he would give the app a reprieve when he takes office on Monday.

On Sunday the Chinese-owned app stopped working for American users, following concerns that their data could be accessed by Chinese officials.

In a statement, TikTok later said it was in the process of “restoring service” just hours after going dark in America.

It thanked the president-elect for “providing the necessary clarity and assurance” and said they would work with Trump “on a long-term solution that keeps TikTok in the United States”.
