Quite often when you re-sign applications the current app entitlements may get overwritten and you may have issues with the app.
You can check the app entitlements prior to generating a new App ID in order to confirm that you have all the correct entitlements.
This can be done by following the steps below:
Pre-requisites you need a Mac with Xcode installed
Copy an existing IPA file into another folder and rename it from yourapp.ipa to yourapp.zip
Extract the zip, you will end up with a Payload folder that contains yourapp.app
Open terminal and navigate to the payload folder (or specify the full path) and run the following command
codesign -d --entitlements - ayourapp.app/yourapp
4.This should give you a list of app entitlements in XML format (see example below)
