TikTok has restored its service to US users after a brief blockage, following a statement from President-elect Donald Trump that provided assurances to the company's service providers. The move comes as a law banning TikTok in the US was set to take effect, but Trump has vowed to issue an executive order to extend the period before the law's prohibitions take effect. The law requires TikTok's Chinese owner, ByteDance, to sell the company to a non-Chinese buyer. The future of TikTok in the US remains uncertain, with some lawmakers expressing opposition to any potential deal that would allow the app to continue operating in the country.
