TikTok suspended its services for US-based users while Apple Inc. and Google removed the platform from their mobile app stores to avoid penalties under a new law, as the social media company awaits a possible reprieve from President-elect Donald Trump to continue operations.

Users on the app were saying their goodbyes, some filming themselves frantically scrolling or sharing final secrets with their followers ahead of the possible ban.

TikTok started going dark for 170 million American users in an unprecedented display of the U.S.-China divide over technology and national security.
