Apple Inc. and Google removed TikTok from their mobile app stores in the US as required by a law that took effect Sunday, after the social media company’s legal challenges failed to head off the measure passed last year to address national security concerns.

As the TikTok ban in the US goes into effect Apple has commented on it. On its support page, the company says that it has removed TikTok as well as other apps by ByteDance from its App Store in the US.
