We are using expo managed to create and publish in App Store the app using the expo to build the iOS using expo build:ios -t archive --non-interactive --no-publish after that we get the IPA file and upload it via xcrun altool --upload-app, but we’ve been receiving the below notification from App Store Team:
ITMS-90725: SDK Version Issue - This app was built with the iOS SDK. All iOS apps submitted to the App Store must be built with the iOS 13 SDK or later, included in Xcode 11 or later. Further, starting April 26, 2021 iOS apps submitted to the App Store must be built with the iOS 14 SDK or later, included in Xcode 12 or later.
Best regards,
