title: Ask for New App Permission
body: <p>I added a feature in my app that requires the background location permission on ios. How do I re-request the location permission to allow 'Always' vs 'While Using'?</p>
  
  <p>Clarification: My app already requests the 'While Using' permission level. With the new feature I need users to up the permission to be 'Always'. However, right now when installing the update over a pre-existing app,  ios isn't promiting the higher level permission and the only way to change it is by going into the Settings app.</p>
