Builds not selectable after account migration — App Store Connect bug

After migrating our app to a new developer account, newly uploaded builds can't be selected during App Store submission. The old (expired) builds from the previous account still appear selectable, but not the new ones. Build is signed with the correct new team certificates, export compliance is set, version numbers match. Has anyone else experienced this post-migration? Support case open with Apple (102823632970) but no response after 6 days.
