Kevin Mayer dramatically announced he was leaving video app TikTok after just three months as CEO on Wednesday, Reuters reported. The former top streaming exec at Disney also served as COO of Chinese parent company Bytdance.

Mayer was Walt Disney Co’s (DIS.N) top streaming executive before becoming chief executive officer of TikTok and chief operating officer of parent ByteDance on June 1. “In recent weeks, as the political environment has sharply changed, I have done significant reflection on what the corporate structural changes will require, and what it means for the global role I signed up for,” Mayer said in an letter to employees. “Against this backdrop, and as we expect to reach a resolution very soon, it is with a heavy heart that I wanted to let you all know that I have decided to leave the company.” ByteDance founder and CEO Zhang Yiming said in a separate letter reviewed by Reuters that the company was “moving quickly to find resolutions to the issues that we face globally, particularly in the U.S. and India”. He said Mayer had joined just as the company was “entering arguably our most challenging moment.”

The latest version of Fortnite will not be available on the iPhone as the court battle between Epic Games and Apple continues. The games maker decried Apple’s App Store “monopoly” and updates of the game are no longer accessible on iOS.

Players of the popular game “Fortnite” on iPhones will not get updates after Epic Games on Wednesday decried Apple Inc’s App Store “monopoly” and said it will not remove a direct payment feature it recently enabled. A legal battle ensued after Epic rolled out its own method of in-game purchases for “Fortnite” on Apple’s App Store earlier this month, rather than using Apple’s required in-app purchase system that charges commissions of 30%.

Fitbit unveiled a new set of products today, including the Sense, as well as the Versa 3. You’d be forgiven for thinking the Sense looks… familiar. The Verge has a rundown of the device’s specs.

The Sense has a few more advanced health tracking features, such as detailed heart rate scans with atrial fibrillation (afib) detection via the electrocardiogram (EKG) app built into the watch (still pending FDA approval). In that way, it’s on par with Apple’s and Samsung’s recent smartwatches (though, Samsung’s EKG capability in the Galaxy Watch 3 isn’t available in the US yet). Where the Sense stands out is with its stress detection features, which it’s pitching as something that’s crucially needed — especially in today’s increasingly stressful world. To take a reading, you hold your palm over the screen and start to breath. The Sense will measure your heart rate, and uniquely, your skin’s temperature will be collected with its electrodermal activity (EDA) sensor. If your skin feels hot, chilled, or clammy, the Sense might be able to make sense of why it’s happening over time. Fitbit’s app will score you on your stress level, with a higher score being better than a lower one.

Public tests of the new version of Apple Maps have reached the UK and Ireland. Justine O’Beirne noted the change, the first time the update has been rolled out beyond U.S. shores.

In the past, Apple has spent between 16 and 49 days publicly testing its earlier expansions… and the more populated the area, the longer Apple has typically spent testing. All of this suggests that Expansion #9 will go live for all Apple Maps users sometime between mid September and early October. Given past patterns, iOS 14 is also likely to be released during this same period—so it seems that Expansion #9’s release might coincide with iOS 14’s.
