title: ITMS-90034: Missing or invalid signature error
body: <p>This is the error message I get while uploading my app binary to iTunesConnect:</p>
  
  <p><code>ITMS-90034: Missing or invalid signature - The bundle 'com.myCompany.myApp' at bundle path 'Payload/myApp.app' is not signed using an Apple submission certificate.</code></p>
  
  <p>I compared the settings with another app of mine I successfully upload and hardly see any difference in the certificates or signing settings.
  Only one thing is different, though: myApp has an extension (Ads blocker) while the other one has none (but I don't think it makes any difference).</p>
  
  <p>I searched through the internet for any fixes or things to be done, but I am left in the same situation, the app is turned as invalid binary for this very issue.</p>
  
  <p>Happy to receive help on that.</p>
