Still to do in App Store Connect (by hand): upload screenshots (iPhone 6.5"/6.9"), add a build, set the age rating (Unrestricted Web Access = Yes → 17+, everything else None), App Privacy = Data Not Collected, and the Widget App-Group portal click.
Heads-up: the version there is 1.0 but the app build is
2.9.838 — they must match, so set the code to 1.0 before uploading.
