I'm running iOS9 beta 4 on an iPhone 6+. I have 5 apps on the appstore. Four install successfully. One downloads fully and then displays the following error:
Unable to Download App
"AppName" could not be installed at this time.
Done Retry
I am able to install this app on iOS 7.0.4 and iOS 8.4 devices.
Looking in iTunes Connect at the Build Details, the only noticable difference is the minimum OS version. The problem app build has a minimum of iOS 5. Others have a minimum of iOS 6, 7, and even 4.3.
The iOS 9 device has 52GB free.
Any ideas what could be causing this behavior?
