Unable to install the iOS build from the third party link and showing white icon only

Question

I am trying to install App from Diawi link on iPhone-7 but every-time its showing plane white iCon as attached below screen.

I have tried the following scenario and all are working fine:

• Tested App on other devices.
• Twice check device UDID (already added with provisioning profile)
• On simulator iCon showing properly for both iPhone7 and 7 Plus.
• Tested with same iOS version on iPhone 6s.

Answer 1

Solved: In my case UDID was incorrect. Client provided me device UDID from third party tools and due to this got incorrect UDID.

• Make sure UDID which you are going to use in your App has been fetched from iTunes not from any third party tools.
