President-elect Donald Trump rode to TikTok’s rescue on Sunday, working on the eve of his new presidency to try to undo a ban effort that he helped initiate during his first term.The popular social-media app started restoring service on Sunday for its 170 million U.

Trump’s proposal exerted pressure on the entire tech ecosystem that makes TikTok available to U.S. users, including app store operators and service providers like Oracle which hosts its servers.

TikTok issued an earlier statement after US users reported being able to access the Chinese-owned service's website while the far more widely used TikTok app itself began coming back online for some users with just a few basic services.
