I got an e-mail from apple.
A sealed resource is missing or invalid. The file at path [thunkablecompanion.app/thunkablecompanion] is not properly signed. Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose “Clean All” in Xcode, delete the “build” directory in the Finder, and rebuild your release target. For more information, please consult [About Code Signing](https://developer.apple.com/library/ios/documentation/Security/Conceptual/CodeSigningGuide/Introduction/Introduction.html)

So what should I do…?
(I have followed docs…!! )

And did you follow the steps for the .mobileprovision file and app specific password?
Have you added push notifications to your app by any chance??
