title: How to link to Update page for our app
body: <p>We prompt users to upgrade their app if they're running an outdated version. When users tap our update button, I use openURL with an address like <code>itms://itunes.apple.com/us/app/our-app-title/id12345?mt=8</code> to load the App Store app to the listing for our app. </p>
  
  <p>With that method, however, the resulting screen has a button labeled "Open" not "Update." If users open the App Store app first, then navigate to our app's listing (or go to the update tab), the button is labeled "Update."</p>
  
  <p>Can I pass the current version as a querystring parameter in the openURL call or is there another way to make sure the Update button is shown? I cannot find current documentation on how to do so. (Everything I find is a few years old and refers to the discontinued phobos tool.)</p>
