TikTok has just ten days until it faces a possible ban in the US. If the Supreme Court declines to halt the law before January 19th, and TikTok isn’t spun off from its Chinese parent company ByteDance, companies like Apple and Google will be forced to stop maintaining the app in their app stores or letting it push updates.

The Supreme Court seemed likely to uphold a new law that could force TikTok to shut down in the U.S., with conservative and liberal justices alike expressing skepticism about the legal challenge.

Congress labeled the app’s Chinese ownership a national security risk and passed a law that would ban the social media platform unless it was sold. TikTok and creators say that violates their free speech rights.
