iOS 13 app uploads fine with Xcode GM to App Connect and displays as "Processing" in App Connect. However, it disappears and I receive an email from Apple showing ITMS-90035: Invalid Signature. Any idea why this generic code-signing error occurs during Processing? Remember, the app uploaded fine with automatic code-signing. Thanks for any help.
