I am running into the same, "ERROR ITMS-90725: "SDK Version Issue. This app was built with the iOS 12.4 SDK. New apps for iPhone or iPad must be built with the iOS 13 SDK or later."This requirement was originally specified on March 4, 2020 and set to go into effect on April 30 per: https://developer.apple.com/news/?id=03042020bHowever, on March 26, Apple announced the rule would go into effect on June 30, instead of April 30. https://developer.apple.com/news/?id=03262020bSo, I'm baffled as to why I'm receiving this error when attempting to upload to App Store Connect.
