New Developer ID team: clean, previously accepted app held for hours on every notarization

My macOS app notarized in 22-24 seconds on every release for months under my
previous Developer ID team. I often shipped several releases a day, even with minor changes. Since
moving to a new Developer ID team (FPRW433858) on Oct 25, every submission of
the same app is held for hours:

  • 85da38d3-1874-458a-9bb5-e4656c770037 (Oct 25 19:09 UTC): still In Progress
    when my CI job hit its 6-hour limit; accepted later.
  • e4bf6e71-58dc-4710-abc0-ba0b459b099f (Oct 29 17:02 UTC): Accepted after
    1h56m. Log: "issues": null, "Ready for distribution". Useless because GitHub CI crashed on it.
  • 0c21d8be-cd60-45c0-b990-f7ebb616201a (Oct 29 19:02 UTC): In Progress, 1.5+
    hours and counting.

Same source, same build pipeline, same Sparkle framework, hardened runtime,
inside-out signing. The only change is the team. The build is clean, and you
have accepted it twice.

I've read the "some uploads are held for in-depth analysis" answers. That is
not an answer I can work with. A bugfix release now takes hours or fails
outright on CI time limits (6h on github), for an app you have already accepted twice under the new Dev ID and countless times under the old Dev ID.

I need concrete answers:

  1. Is team FPRW433858 flagged for in-depth analysis, and why?
  2. When does that end? After how many accepted submissions, or on what date?
  3. Is there anything I must do on my side? If so, what exactly?

If nothing on my side causes this, please clear the team or escalate it to
someone who can. I cannot accept to wait hours/days on app releases that are straightforward otherwise.
