The BBC has advised staff to delete TikTok from corporate phones because of privacy and security fears.
The BBC seems to be the first UK media organisation to issue the guidance - and only the second in the world after Denmark's public service broadcaster.
The BBC said it would continue to use the platform for editorial and marketing purposes for now. TikTok has consistently denied any wrongdoing.
The app has been banned on government phones in the UK and elsewhere.
Countries imposing bans include the US, Canada, New Zealand and Belgium, while the same applies to anyone working at the European Commission.device."
Staff with the app on a personal phone that they also use for work have been asked to contact the corporation's Information Security team for further discussions, while it reviews concerns around TikTok.
BBC News has its own TikTok channel with 1.2 million followers, and has recently recruited journalists to work specifically on creating content for it. A separate BBC account, which shares BBC programme clips, has more than four million followers.
When asked, by BBC News, why the BBC was continuing to indirectly encourage use of the app by audiences while removing it from many corporate phones, the corporation said that it was giving guidance to staff with access to sensitive data, and was not issuing a public warning about the general use of TikTok.
TikTok said it was disappointed with the BBC's decision.
A spokesperson said: "The BBC has a strong presence on our platform, with multiple accounts from news through to music reaching our engaged community both in the UK and around the world.
"We believe these bans have been based on fundamental misconceptions and driven by wider geopolitics.
"We remain in close dialogue with the BBC and are committed to working with them to address any concerns they have."
Other social media platforms have also faced criticism over privacy and data, but they are mainly US-owned - whereas ByteDance has faced claims of being influenced by Beijing.
While there has been no solid proof of this, there have been a number of incidents which have raised suspicions despite TikTok's repeated denial that it has ever shared data with the Chinese government. It asserts that all Western users' data is stored outside the country.
For example, a US TikTokker shared a video criticising the Chinese government's treatment of the Uighur Muslims, and it was taken down. TikTok said this was a mistake.
This has added to the nervousness of governments and security specialists - despite the firm's consistent denials.
All Western social networks, which TikTok says gather similar data on their users, are officially blocked in China.
China has accused the US of spreading disinformation and suppressing TikTok. Both former President Donald Trump and current President Joe Biden believe the platform should be sold to a US company.
