I just updated to iOS 9.1 and tried to install the vShare app and I got a error: Untrusted Enterprise Developer iPhone distribution: "Shandong Electric Power Engineering Consulting Institute Corp., Ltd" has not been trusted on this iPhone. Until this developer has been trusted, their enterprise apps will not be available for use. I think that the main problem is because the Vshare app is signed with enterprise certificate that is not yet trusted on the device. On the old software there was a option to click Trust, but here I can't find this option, and I can't use the app on my iPhone. Here's the screenshot from my iPhone.

How to fix this problem and use this app on my iPhone. I ned it because the iOS 9.1 jailbreak is not released yet.
