Some TikTok users think the algorithm is different now, but did something really change after the short-lived ban of the app in the U.S.?

Three days after ByteDance's TikTok went dark and then was quickly revived in the United States, users who deleted the app were anxiously checking iPhone and Android devices to find it still unavailable to be downloaded again.

The TikTok ban won't be enforced until April, but there will be plenty of contentious negotiations between China, the U.S., and prospective buyers in the meantime.

Trump said the government should be a half owner of TikTok's U.S. business in return for keeping the app alive, and threatened China with tariffs if it failed to approve a deal.
