President-elect Donald Trump says he wants service providers like Apple and Google to put TikTok back online in the US, and proposed creating a joint venture where the US owns 50 percent of the app.

TikTok ceased operations for 170 million U.S. users on January 19 after a law banning the app due to national security concerns came into effect. The shutdown has caused significant disruption, particularly among younger users.

Users on the app were saying their goodbyes, some filming themselves frantically scrolling or sharing final secrets with their followers ahead of the possible ban.
