title: User Permission to Sync with Contacts
body: <p>I have an IOS app  </p>
  
  <p>The Requirement: Sync Phone Contacts with App Contacts </p>
  
  <p>Condition: When Reinstalling an updated version of the app onto the phone,</p>
  
  <p>User is NOT prompted by IOS SYSTEM for permission to sync with Phone contacts.</p>
  
  <p>USER had previously granted permission to the test flight version, so it seems our updated version does not prompt the user for permission to Access Camera and Sync Contacts because a flag has already been set establishing permission for the app to automatically sync in the background?</p>
  
  <p>QUESTION:
  Do we need to require the user to delete the previous Test Flight app from the phone in order to allow IOS to request user permission to sync contacts?</p>
  
  <p>Al Comments welcome</p>
  
  <p>Thank you</p>
