Posting another data point in case it helps the team see the pattern.
First-time notariser, Apple Developer Team ID Q9LV8L6XZ9. Four submissions (all Ping.zip, Electron app, arm64, hardened runtime, signed with Developer ID Application) submitted yesterday between 19:13 and 20:27 UTC. All still In Progress 19 hours later with no state change whatsoever.
Submission IDs:
3861f4af-ec5e-47f9-93c7-d1583ba98863c5b200a0-5c13-41cf-8376-83eab8d9afe4cda1991e-1779-4d1d-9448-d464e64e930a4f374650-4343-4aa8-8afe-03b150dd52b9
xcrun notarytool log <id> returns "Submission log is not yet available" for every one of them — so Apple hasn't produced any analysis output, successful or not.
I appreciate that "in-depth analysis" can take longer for first-time uploads, but 19+ hours on four identical submissions with zero progress looks less like deep analysis and more like the jobs are stuck. Is there anything on the account/team-ID side that might be blocking them from entering the analysis pipeline?
Happy to provide anything else that would help.
