TikTok is inching closer to a potential ban in the US. So what's next?

TikTok's future in the U.S. appeared uncertain on Friday after a federal appeals court rejected a legal challenge to a law that requires the social media platform to cut ties with its China-based parent company or be banned by mid-January.
