ios - iOS8 Beta Ad-Hoc App Download (itms-services)

Question

I have an ipa built using my Wildcard profile. I am hosting the ipa, and my testers are downloading it on our devices.

For iOS7+ devices it is working fine.

I have installed the iOS8 Beta on one of my devices. If I install my app from the app store it installs and works fine. If I try and install an ipa version I get an "Unable to Download App" error.

I am using this style of URL to download:

itms-services://?action=download-manifest&url=https://url-to-plist.plist

My plist looks like:

download/install progress gets about 2/3 of the way round and then I get the error.

The console information looks like this:

Specify a 'display-image' and 'full-size-image' as described here: http://www.informit.com/articles/article.aspx?p=1829415&seqNum=16

iOS8 requires these images
