Notarization stuck "In Progress" — both DMG and ZIP, Electron app, 5+ attempts

All notarization submissions remain stuck "In Progress" and never complete. Tested both DMG and ZIP formats — same result. This has been consistent across 5+ attempts on March 29, 2026.

App: Electron desktop app (arm64), signed with Developer ID Application, hardened runtime enabled, secure timestamp present.

DMG submissions (all stuck):

  • 568cc9c3-e711-41ba-99ce-6af5a1860ae9 (10 min timeout)
  • e0a345c3-ddf8-4771-bdda-e0bc133ff723 (20 min timeout)
  • 6757e5a9-d95b-45b3-95d5-41cb23384bea (20 min timeout)

ZIP submission (.app bundle via ditto, ~207MB):

  • Also stuck "In Progress" for 10+ minutes

notarytool log returns "Submission log is not yet available" for all submissions.

Developer ID Notary Service shows "Available" on System Status page.

Environment: macOS GitHub Actions runner (macos-latest), latest Xcode, xcrun notarytool.

Seeing similar reports from other developers this week. Is there a known service issue?
