TikTok went dark for a few hours in the U.S. before the ban was suddenly reversed Sunday. Here's what to know about President Trump's executive order.

We now know what a TikTok ban in the U.S. looks like: TikTok goes dark, users can't access their accounts if they were created in this country, and VPNs mainly seem to work on the web. The question now is whether we'll see a true ban happen later this year, or whether we'll see ByteDance sell some or all of the app instead.

President Donald Trump has signed an executive order to temporarily delay the U.S. TikTok ban, directing the Department of Justice to hold off on enforcing the controversial law for 75 days. This doesn't mean TikTok has been saved, though.
