Apple TestFlight (beta) app won't install

Question

We have been using Apple's TestFlight facility to distribute a beta version of our app for a few months now (migrated from the older TestFlight service before it was merged into the AppStore). Things worked smoothly until today. After uploading a new beta build to TestFlight, the app no longer installs on the device (iPhone 6 with iOS 8.3).

When opening TestFlight app and tapping "Install" to install the latest beta version of the app, TestFlight downloads the app, but when the installation completes, the app icon vanishes. The button in TestFlight app changes back to "Install", but tapping on it shows an alert:

"Could not install [app name]. The app is currently downloading"

We've tried:

• Restarting the phone
• Resetting all settings on the phone (factory defaults)
• Upload a new build to TestFlight.

This looks like an issue with iOS 8.3. Installing on devices with earlier iOS version did succeed:

• iPhone 6, iOS 8.1.2
• iPhone 4S iOS 8.2

Has anyone encountered this issue and found a solution?

2. Add user (technical role)
3. Check mark at internal users at my app.
4. Uncheck/Check TestFlight Beta Testing switch.
5. Open testflight through mail link.
6. Install.

Answer 5

In some cases it may be a simple temporary malfunction of testflight. I suggest to try waiting a few hours before doing hard tests such as regeneration of certificates.

Answer 6

只需退出 Testlfight 并重新启动即可为我修复它

Answer 7

最简单的解决方案是将飞行模式设置几秒钟，重新激活连接并再次尝试下载。

Answer 8

I've had this issue recently, I tried uninstalling testflight and downloading it again from the app store.

It wouldn't let me download, I turned my phone on and off and then I could download from the app store as well as testflight.
