target detection fail with new signing

Hello!

I have built an app using vuforia 3.0 and unity 4.5.5, and deployed it for iOS devices. The app works fine as signed with the code signing certificate and key for my team.

But when we sent the IPA to our client and they resigned it, they say that the camera is not picking up the tracker and displaying the AR content. I have tried doing a little Google research into this with no luck.

When the client downloads the app with our signing from a third party site (Test Flight) it works fine. This to me eliminates the possibility that they are simply using the app in bad lighting or some similar environmental issue.

It is only when they try to send it out through their own deployment process that tracker detection stops working. They specified that the camera itself was still working, ie there was not a black screen. In addition, the GUI buttons and other elements of the program are all functioning fine. Just the AR wasn't working.

Has anyone experienced a similar problem, or have any ideas on how to correct it?

Thanks so much!

Hi. I am also experiencing the same problem. I did all the necessary setups but when I try to detect my image target, the model is not displaying.
also, I used unity 4.3 and vuforia sdk 3.0.9. I am using xcode 5.0.1 in building my ios app. I test it in my ipod touch 4G (jailbroken).
