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.

But on Sunday, TikTok has returned for some users in the US “in agreement” with its service providers, the company said. A pop-up displayed within the app thanks users for their patience and says its restoration comes “as a result of President Trump’s efforts.”

With President-elect Trump adding uncertainty around whether a TikTok ban will go into effect, the focus is now turning to companies like Google and Apple.
