Notarization stuck "In Progress" for 4+ days — new Developer ID account, first submission

My notarization submission has been stuck in In Progress for over four days (100+ hours) and I'd appreciate a status check.

• Submission ID: e1b209de-c30b-42b7-b431-afaf39e9681b
• Team ID: Q77SU7HBNQ
• Submitted: July 28, 2026 (late evening, US Eastern) via xcrun notarytool submit
• Payload: a zip containing a signed macOS app bundle (arm64, Developer ID Application certificate), about 90 MB compressed

Additional context:

1. This is a brand-new Developer ID account — these are my first-ever submissions.
2. An earlier submission (2b1c4738…) appeared to be lost entirely: after several hours, notarytool info and notarytool history no longer returned it, so I resubmitted the identical zip as the submission ID above.
3. The current submission definitely exists — notarytool info returns it and reports In Progress on every poll, and has for 100+ hours.
4. I have not resubmitted again, per the guidance in similar threads that first-time submissions can be held for extended analysis.

I understand from other threads (e.g. 821679, 818256, 814827, 821858) that first submissions from new accounts can be held for in-depth analysis. Could someone take a look at this submission and let me know whether it is still progressing normally, or whether something is wedged and I should resubmit?

Thank you!
