I updated my Flex SDK with build 32.0.0.103 and iTC no longer sends me the "Starting March 2019, all iOS apps submitted to the App Store must be built with the iOS 12.1 SDK or later..." warning.
This is good, but now Apple is rejecting the app because of invalid architecture: "Invalid architectures - This app has invalid architecture, and may have been built with invalid build settings or incompatible tools." You can read about this issue here: https://forums.adobe.com/thread/2594846 <https://forums.adobe.com/thread/2594846> It seemed to just be about minimum target OS but that appears to not be true. Here is a bug in Adobe Tracker about this issue: https://tracker.adobe.com/#/view/AIR-4198796 <https://tracker.adobe.com/#/view/AIR-4198796> This may be strictly an AIR 32 bug that will prevent everyone from uploading apps to iTC. Have any of you out there built an app and successfully uploaded to iTC with AIR 32.0.0.103? If not, really appreciate if everyone on this forum would vote for this issue which has 10 vote so far. Thanks.
