TikTok will shut down entirely in the US on Sunday without intervention from the US Supreme Court, unnamed sources have told Reuters. That would go beyond the ban’s requirement for app stores to stop offering downloads of the app, but not immediately halt use of it.

TikTok plans to shut its app for U.S. users from Sunday, when a federal ban on the social media app could come into effect, unless the Supreme Court moves to block it, people familiar with the matter said.
