I am getting Untrusted App Developer message when I am trying to run Appy Pie's test App on my iPhone with iOS9, what should I do?

This is a new security added by Apple on its IOS9 Upgrade. Now Once the App is installed, to run Appy Pie test App on an iPhone with iOS9, you would need to first trust Appy Pie as a Developer and here is how you can do that:

1. Go to: Settings >> General >> Profiles
2. Under ENTERPRISE APP, choose Onsinteractive Solution Pvt Ltd.
3. Tap Trust Onsinteractive Solution Pvt Ltd.
4. Tap Trust in pop up.
5. Now, try running your test app again and it should work.
