I have exactly the same problem, except using the expo build:ios --release-channel command. I built successfully 5 hours ago with exactly the same codebase. The only changes I’ve made are to the version, buildNumber, and versionCode properties in the app.json.
Any help here or information about what’s going on would be greatly appreciated.
The same or similar issue was reported here: Unsupported SDK version error when trying to build for iOS and Android (sdk version 33.0.0)
Thanks so much!
