title: Do we need the same bundle Id for the Extensions to push an Update to the App store
body: <p>We are having an app in the App store and we need to push a latest update of the app to the store.
       We have lost the Distribution certificate, profiles, AppId with which the app has been pushed to store previously. We only have the 'Bundle Id' of the app from the 'itunes Connect' account.
      The App is having an extension (Today extension is used in the app). My question is as I am having only the bundle Id of the main app(ie, com.xx.xxapp). Can I just create the bundle Id for my extension app with main app bundle id as prefix (ie,  com.xx.xxapp.todayExtention). As I did not know the bundle Id of the extension used in the previous push. Will a mismatch in the bundle Id of the extension used in the old push and new push cause issues for the users to get the update of my app.</p>
