Summary

Codex Mobile restores an old revoked Mac connection and cannot load messages. The iPhone app shows the old Mac connection automatically, but opening any thread fails with 403.

Environment

  • Codex Desktop: 26.513.31313
  • macOS: 26.4.1
  • iPhone: ChatGPT/Codex mobile app with Codex Mobile enabled
  • Connection shown on iPhone: MacBook-Air-de-Djalmir.local

Error

On iPhone, opening a thread shows:

Error loading messages: There is a problem with your request. (403, e7fec3e2-e528-4110-929b-909d742fd708)

What happened

  1. iPhone was connected to Codex Desktop.
  2. The connection had issues.
  3. I revoked the iPhone from Codex Desktop.
  4. I tried to reconnect using "Manage connections" / "Add device" on Desktop.
  5. Desktop shows a QR code.
  6. Scanning the QR code sends me to the iPhone app.
  7. The iPhone app immediately restores the old Mac connection instead of creating a clean new connection.
  8. The old connection lists chats, but opening any chat fails with 403.

Things already tried

  • Quit/reopened Codex Desktop.
  • Revoked the iPhone from Desktop.
  • Deleted and reinstalled the iPhone app using Delete App, not Offload App.
  • Reset local Desktop remote/mobile state.
  • After reset, Desktop generated a new local environment_id, but iPhone still restored the stale old connection.
  • The Codex Desktop UI only lets me generate a QR code; iPhone UI does not offer a way to delete/remove the stale Mac connection.

Expected behavior

After revoking a device, the iPhone should either remove the old Mac connection or allow me to delete it, and scanning a new QR code should create a fresh working connection.

Actual behavior

The iPhone restores the old connection and every thread fails with 403.

Request

Please provide a way to clear stale Codex Mobile / remote-control enrollments, or fix backend cleanup after revoke.

What steps can reproduce the bug?

  1. Connect an iPhone to Codex Desktop using Codex Mobile / Manage connections.
  2. Revoke the iPhone from Codex Desktop.
  3. On Codex Desktop, open Manage connections and click Add device.
  4. Scan the new QR code with the iPhone.
  5. The iPhone app opens and immediately restores the old Mac connection instead of creating a clean new connection.
  6. Open any thread from that restored Mac connection.
  7. The iPhone app fails to load messages with a 403 error.
