TikTok service is back online in the US, but the app is unavailable for download in the US - here's when it might return.

While TikTok has been restored for millions of American users after going dark, the app still isn't available on Apple's App Store or Google Play.

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.”
