Notarization submissions stuck In Progress then disappear, x64 only
Team ID CJLCWP5NP3, app Write (com.connerkennedy.write), Xcode Command Line Tools notarytool 1.1.3 (42), macOS 26.6.2 build 25G83.
Every x64 (Intel) notarization submission for this app gets stuck at status In Progress and never resolves. After roughly 11 to 12 hours, the submission disappears entirely: notarytool info with that submission id starts returning "Submission does not exist or does not belong to your team," and the submission no longer appears in notarytool history at all, not as Accepted, Invalid, or Rejected, just gone.
This has happened identically on three consecutive x64 submissions. The submission ids and creation times, in UTC, are: b532a8a4-1dab-4eab-b37c-81b53b3573bb, created 2026-09-20 20:25:48 3a1ea67f-f88d-43e6-9ef5-62a6de1aa5d2, created 2026-09-20 21:22:16 8bc19842-e93a-4ea7-b3cc-3c1aeb20b423, created 2026-09-21 11:28:53 All three followed the same pattern: stuck in progress, then vanished roughly 11 to 12 hours later.
In sharp contrast, every arm64 (Apple Silicon) submission from the same team, same day, same build pipeline, succeeded normally, typically within a few minutes. Five separate arm64 submissions across September 8 through September 20 all came back Accepted with no issues.
This is the first time this team has ever submitted an x64 build for notarization. Every prior successful submission was arm64. That is the only meaningful difference we can find between the submissions that succeed and the ones that get stuck.
Before concluding this is server side, we ruled out several things on our end. It is not a local network or VPN issue, since we reproduced it with a VPN active, after fully disconnecting the VPN, and after a full machine reboot. It is not local resource pressure, since we reproduced it with over 18 GB of free RAM after a reboot, the same conditions under which arm64 succeeds instantly. It is not the specific file, since we reproduced it with a completely fresh rebuild of the app and also when submitting a dmg instead of a zip. It is not our build tooling, since we bypassed electron-builder's built in notarize step entirely and submitted directly with xcrun notarytool submit and info, with the same result. And it is not a one off blip, since it reproduced three times in a row over about 36 hours, always the same stuck then vanished pattern, with arm64 unaffected the whole time.
We would appreciate help understanding why x64 submissions under this team are getting stuck and then disappearing after 11 to 12 hours, while arm64 submissions from the same team notarize normally. Either an explanation of what is happening so future x64 submissions process normally, or confirmation that this is a first time x64 review hold that needs manual clearing on Apple's side, would be very helpful. Happy to provide the actual zip we submitted, full notarytool logs, or anything else that would help investigate
