Warning ITMS-XXXXX (Certificate & Locale)
I see the Certificate noted in the release notes for 30.0.0.96 -- not the locale though.
These appear in the Application Loader after upload - however, the App is still accepted.
WARNING ITMS-90722: "Certificate Expired. The signing certificate "CN=Apple Worldwide Developer Relations Certification Authority, OU=Apple Worldwide Developer Relations, O=Apple Inc., C=US" with serial number 25 used to sign xxx.app has expired. Learn more (https://help.apple.com/xcode/mac/current/#/dev154b28f09)."
WARNING ITMS-90176: "Unrecognized Locale - The locale names used in localization directories at ( "Payload/xxx.app/AccountKitStrings.bundle/Resources/cb_IQ.lproj" ) are invalid. iTunes supports BCP47 but not the UN M.49 specification. Refer to the Language and Locale Designations guide at https://developer.apple.com/library/content/documentation/MacOSX/Conceptual/BPInternational/LanguageandLocaleIDs/LanguageandLocaleIDs.html for more information on naming your language-specific directories."
