Hello to all,I have read almost all the posts related to this error, both on this forum and on other external ones, but apparently the origin is varied and often unknown.Like everyone, I compiled the App and sent it via Transporter, but the result is "ITMS-90111: Invalid Toolchain - Your app was built with a beta version of Xcode or SDK ...."These are the environmental characteristics:MacOS Catalina Version 10.15.2Xcode: 11.3 (15712)Tools: 11.3 (64532.3)SDK: iOS: 13,2: (17B102) iOS Simulator: 13,2: (17B102) macOS: 10,15: (19B90) 19,0: tvOS: 13,2: (17K90) tvOS Simulator: 13,2: (17K90) watchOS: 6,1: (17S80) watchOS Simulator: 6,1: (17S80)Note: the App is the first build and contains purchases in the AppStore and admob advertising.I also recreated all the certificates.I also tried compiling with MacOS High sierra (xcode 10.1), same result.Clearly I don't have beta software, what can be the cause? does it happen to someone else?Thank you
