Amazon has said an email sent to employees asking them to remove the video-sharing app TikTok from any mobile device that can access their company email was sent in error.
An internal memo sent to staff earlier on Friday had said employees should delete the app over “security risks”.
The app, owned by a Chinese company, has come under scrutiny because of fears it could share data with China.
TikTok said it did not understand Amazon’s concerns.
“This morning’s email to some of our employees was sent in error. There is no change to our policies right now with regard to TikTok”, a company spokesperson told the BBC.
But earlier on Friday, a memo sent to staff seen by multiple news outlets stated that the app must be removed from mobile devices.
“Due to security risk, the TikTok app is no longer permitted on mobile devices that access Amazon email.
“If you have TikTok on your device, you must remove it by July 10 to retain mobile access to Amazon email”, it read.
TikTok said the company had not received any communication from Amazon before the email went out.

Artificial intelligence-powered short video app TikTok is one of the most downloaded mobile apps in the world, and its popularity has only grown during the coronavirus lockdown.
This has drawn the attention of the Trump administration – on Monday, Secretary of State Mike Pompeo told Fox News that it was considering a ban on Chinese social media apps.
