TestFlight is unable to complete testee app upgrades

Question

Recently, we found our internal testers and external testers can't update our new prerelease app.

We are using developer provisioning file to sign binary code. The prerelease app can be verified by itunesconnect. It can be submitted to app store successfully. Than our testers tried to use TestFlight to update the app. They pressed Update button beside the app icon in the TestFlight. The TestFlight never finish its job. The progress circle wouldn't complete.

Version: TestFlight Version: 1.0.2(55), XCode Version: 6.3 (6D570), iOS Version: 8.1(12B411) & 8.2(12D508) & 8.3(12F70)

We have tried 3G network and WiFi network. We have tried all different Apple ID in TestFlight.

Answer 1

对于Beta版本，您必须使用与发布相同的分发配置文件。

Answer 2

I can't say this solution will suit for all other same scenarios, but for my case I got answer from Apple Bug Reporter's engineer.

Engineering has provided the following feedback regarding this issue:

We have figured out the issue. The TestFlight app doesn't correctly handle apps that include leading 0s in their versions strings. Versions like 1.6.02 or 3.5.04 will fail to complete the install.

Until this is fixed, please workaround it by using version numbers without leading zeros (1.6.02 -> 1.6.2 or 3.5.04 -> 3.5.4).

Sorry for the inconvenience and thank you for spending so much time gathering information on this issue, it really helped!
