What issue are you seeing?

Symptoms:

• iPhone ChatGPT shows “Waiting for desktop...”
• Codex desktop has a mobile icon and Connections > Add device
• clicking the mobile icon opens a black/empty page
• Add device shows a QR code, but scanning it only reopens ChatGPT on iPhone to the same “Waiting for desktop...” page
• logging out/in changed the UI behavior but did not fix pairing

Local evidence:

• Codex desktop repeatedly enables remote control but finds zero clients/connections
• feature bootstrap cache stays empty
• desktop log shows a post-login bootstrap error for user.custom.workspace_type

Summary
Codex desktop on macOS cannot complete mobile pairing with ChatGPT on iPhone.

Repro steps

1. Open Codex desktop on Mac.
2. Click the mobile icon near Settings, or go to Settings -> Connections -> Add device.
3. Scan the QR code with the ChatGPT iPhone app.
4. ChatGPT opens, but stays on “Waiting for desktop...”.
5. On Mac, the mobile-connect UI may open as a black/empty page.

Expected
The iPhone should pair with the running Codex desktop session.

Actual
The iPhone remains stuck on “Waiting for desktop...”, and the Mac never completes pairing.

Observed details

• Before logout/login, a “Mobile connect” option was visible.
• After re-login, the UI changed, but pairing still failed.
• Clicking the mobile icon opens a black/empty page.
• Settings -> Connections -> Add device shows a QR code, but scanning it just reopens ChatGPT to the same waiting screen.
