TikTok has resumed operations for existing users in the U.S. following a brief shutdown, but new downloads remain restricted in the Apple and Google app stores. This situation arises from a bipartisan law addressing national security concerns regarding the app's Chinese parent company, ByteDance. Former President Trump extended the ban's enforcement, allowing ByteDance more time to sell its U.S. operations. Both Google and Apple have paused new downloads to avoid potential penalties. The future of TikTok hangs in the balance as legal challenges and acquisition talks continue.
