title: IOS14 tracking permission for apps compiled with IOS 13
body: <p>In IOS14 in order to use <code>Advertising Identifier</code> you need to request for permission but what's the behaviour for apps already available on AppStore (Compiled with IOS13 SDK)?</p>
  <p>I have updated a device to IOS14 Beta 4 and downloaded app from AppStore. Once I open the app it's not automatically asking for any tracking permission and <code>Advertising Identifier</code> is <code>00000-0000-0000</code>.</p>
  <p>Does this mean I must submit an app update compiled with IOS14 SDK and request for tracking permission otherwise <code>Advertising Identifier</code> won't be available?</p>
