Codex.app QR linking from ChatGPT iOS stalls for account formerly tied to Team workspace

Open 💬 2 comments Opened May 29, 2026 by ryofukutani

What happened?

ChatGPT iOS -> Codex.app QR-code linking does not complete for an account that was previously associated with a Team/Teams workspace and later continued as an individual/personal account using the same email address.

The QR code is scanned on the iPhone, but the flow does not proceed afterward. Repeated retries and app/Mac restarts do not resolve the issue.

A separate, straightforward account created directly and signed in with Google SSO can complete the same iPhone-to-Mac Codex.app linking flow successfully, so this appears account-state dependent rather than a general local network, QR scanner, or device issue.

Account history that seems relevant

  • The affected email address was originally used primarily with a Team/Teams workspace account.
  • Later, an individual/personal account was added/used with the same email address.
  • The Team/Teams account/workspace was then discontinued/removed.
  • The affected account still signs in with Google SSO.
  • After that history, ChatGPT iOS -> Codex.app QR linking never progresses after QR scan.
  • A clean/simple Google SSO account without that workspace history links successfully on the same general setup.

No email address, workspace ID, or account-identifying details are included here because this is a public issue. If OpenAI support needs account-specific identifiers, I can provide them through the private Help Center support channel.

Expected behavior

After scanning the Codex.app QR code in ChatGPT iOS, the mobile-to-Mac linking flow should continue and connect ChatGPT on iPhone to Codex.app on macOS.

Actual behavior

The QR code is accepted/scanned on iPhone, but the linking flow does not continue. The Mac remains unconnected.

Steps to reproduce

  1. Use an OpenAI account that was formerly associated with a Team/Teams workspace and later continued as an individual/personal account using the same email address.
  2. Sign in to Codex.app on macOS.
  3. Start the mobile-to-Mac linking flow in Codex.app and display the QR code.
  4. Open ChatGPT on iPhone using the same affected account.
  5. Scan the QR code from the iPhone.
  6. Observe that the flow stalls and does not complete.

Environment

  • Codex.app: 26.519.81530 (bundle version 3178)
  • macOS: 26.2 (25C56), Apple Silicon / arm64
  • ChatGPT iOS app: version not captured yet
  • iOS device/version: not captured yet
  • Sign-in method: Google SSO

Notes

This looks like a stale account/workspace/device-linking/auth state issue specific to accounts that previously had Team/Teams workspace association under the same email address.

Additional details from the affected flow:

  • ChatGPT iOS app version: 1.2026.132 (26051406691)
  • Codex.app version on macOS: 26.519.81530 (3178)
  • On iPhone, after tapping Connect and scanning the QR code, the flow reaches a waiting screen and then stalls indefinitely.
  • The iPhone screen says: Waiting for the desktop app... / Japanese UI: デスクトップアプリを待っています...
  • The subtitle says: To connect, follow the instructions in the desktop app. / Japanese UI: 接続するには、デスクトップアプリの指示に従ってください。
  • The Mac desktop app shows no visible state change after the QR scan. It behaves as if the mobile-side scan/linking event is ignored or never reaches the desktop app.
  • Restarting and retrying does not change the behavior.

This further supports that the QR scan itself is recognized on the iPhone, but the handoff/linking state is not completed for this affected account.

More evidence that this is account-state specific rather than local environment specific:

  • iPhone model: iPhone 15 Pro
  • iOS version: 26.5
  • The exact same iPhone, Mac, network, ChatGPT iOS version, and Codex.app version can complete the mobile-to-desktop linking flow successfully with another OpenAI account.
  • The affected account fails consistently in that same environment and stalls on Waiting for the desktop app... after QR scan.

So the issue does not appear to be caused by the local device, iOS version, macOS version, Codex.app install, QR scanning, or network. The behavior points to account-specific auth/linking/workspace state for the affected account.
