(Telecompaper) Kevin Mayer has resigned as CEO of TikTok, just over three months after taking the job, the New York Times reports. In a note to employees seen by the paper, Mayer said that a series of changes to TikTok's structure prompted him to leave. This follows the US government ordering a ban on doing business with TikTok's parent company, China-based ByteDance, and talks to sell TikTok's US operations.
