ByteDance restored TikTok service in the United States on Sunday night, but major tech companies like Apple and Google have yet to restore downloads of the app. With no way to update TikTok, app rot may soon set in.

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

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.

If you search for TikTok on the App Store, you’ll see a message saying, “TikTok and other ByteDance apps are not available in the country or region you’re in,” while Google Play says, “Downloads for this app are paused due to current US legal requirements.”

TikTok faces an uphill battle getting back in app stores, even with Trump's executive order that says he won't enforce the TikTok ban for 75 days.

Apple and Google removed TikTok from their app stores Saturday, complying with a law requiring China's ByteDance to divest the social app or see it face an effective ban in the U.S.

TikTok remained unavailable on Apple and Google app stores in the U.S. on Tuesday, a day after President Donald Trump signed an executive order delaying the enforcement of a ban on the popular Chinese-owned short-video app by 75 days.

TikTok restored access to U.S. users Sunday afternoon following a brief outage, after a federal law took effect that bans companies from hosting TikTok and other ByteDance-owned apps unless ByteDance divests from the apps,
