I have several tester who have registered to testflight and connected their devices... they have different ios models... iOS 6 and above... but all of them share the same problem.
When they click the install button of an app from "safari" or the "testflight" app itself...
the app starts to download... reaches about 90% and an error message appears...."UNABLE TO DOWNLOAD APPLICATION. the "app" could not be installed at this time.
Now i have about 30 testers... 7 of them have the same issue... the others have succesfuly installed the app with no problem what so ever...
It seems completely random bug to me as there are no correlations between the phone models or ios versions... which are by the way all 6 and above....
So... what do i do. please help
Insufficient Storage- If your Android device is too full, it causes the package installer to malfunction, leading to the 'App not Installed' pop-up. Even a corrupted Internal Storage Card or an SD card which is not mounted properly may lead to clogged storage and thus give you the App not installed error message.
Installing from TestFlight Installing beta apps in TestFlight is easy. Install the latest verision by selecting the app and tapping “Install.” After the app installs, the button will change to “Open.” You can open the app from there or from your home screen.
Once you're logged into App Store Connect, click on your app and then click on TestFlight. Your processed build will appear under the Version you set before creating the archive, Version 1.0 in my case.
there could be many reasons of it Below are some of those mentioned
You are using Developer profile instead of Adhoc Distribution profile
You are using app identifier that is different from the one that belongs to your profile
There could be issue with iCloud/Gamecenter enabled/disabled
In any case ask the testers to connect the device to PC/Mac open iPhone Configuration Utility and see the logs after you press install from the build in testflight.This will give them a deep insight of whats going wrong there.Hope this helps
For me Setting Build Active Architecture to NO... works and installed successfully
I just had the same problem, it seems testflight is down. It was not showing in the system status from the beginning but they updated it to reflect the period I experienced the problem.
I had around 70 testers, only one was able to download, that tester just kept on retrying.
For my case, uninstalling/reinstalling the TestFlight app from testers' phones seemed to help, as though the installs had got into an irretreivably bad state.
For anyone else going through this, worth noting that iTunes Connect support couldn't help, and Apple Developer Support wouldn't help.
