Other cybersecurity experts said TikTok might not become inaccessible overnight, but rather that the user experience in the U.S. will degrade over time. Chetty agreed, and said the app might also lose popularity over time if it's banned.

The law could go into effect on Sunday, so here's what could happen. The US Supreme Court heard arguments Friday about whether or not to uphold a law that effectively bans the social media app TikTok.

TikTok may be banned in the U.S. over the weekend, but Americans are heading to another Chinese-owned video platform: RedNote.

BEIJING (Reuters) -Chinese social media app RedNote has been thrust into the limelight after more than half a million TikTok users recently joined the platform in protest against a likely imminent ban on the short video app in the United States.
