The app’s availability in the U.S. has been thrown into jeopardy over data privacy and national security concerns.

TikTok had been removed from the app stores when it briefly went dark last month amid compliance with a law passed to ban it.

The law requires TikTok's Chinese parent company, ByteDance, to sell its U.S. assets in order to continue operating in the U.S. While the law only mandated that ByteDance remove TikTok from app stores in the U.S. if it failed to meet the sale deadline, company executives decided to shut down the app entirely.
