TikTok CEO Kevin Mayer resigned just three months after joining, and only days since the firm sued the Trump administration over an executive order effectively banning it in the US.
He will be replaced by US GM Vanessa Pappas on an interim basis.
The resignation comes at a time as it tries to persuade both the US and India that it is not a security threat while holding discussions with prospective buyers after a second US order demanding the sale of its US operations.
Mayer was Walt Disney’s top streaming executive before accepting the role of TikTok CEO, and ByteDance COO.
ByteDance is the parent company of TikTok.
Mayer said he decided to leave the company after doing a significant reflection on what the corporate structural changes will require, and what it means for the global role he signed up for.
