Yes Sir, thank you for quick response, Our application’s bundle ID’s are:
old: com.digicorp.30secapp
new: com.30sec.30secapp
And I am pretty sure they did install the latest build with the new bundle ID. Right now if I run the application from the simulator/ through Xcode then its showing the new Bundle ID.
But If I download it through test flight then it shows the old bundle ID.
And again thanks for looking into it @bonnell .
