Codex product switcher missing in macOS app 26.715.72359; older builds work

What version of the Codex App are you using?

ChatGPT/Codex desktop app version 26.715.72359 on macOS, Apple Silicon.

What subscription do you have?

ChatGPT Pro / Business workspace with Codex enabled. Codex was previously available and used on the same account and machine.

What issue are you seeing?

The global ChatGPT/Codex product switcher is missing. The app opens only in ChatGPT mode, with no visible way to enter Codex.

This has been happening across recent app builds for weeks. Installing an older copy of the app obtained from another Mac restores Codex on the same account and machine, which suggests a desktop-app regression rather than an entitlement or workspace-permission issue.

Steps already attempted

• Fully quit and reopen the app
• Sign out and sign back in
• Reinstall the latest app
• Open codex://threads/new
• Confirm Codex access is enabled for the Pro/Business workspace

None restores Codex in 26.715.72359. The deep link opens ChatGPT mode instead.

Expected behavior

The top-left product switcher should expose both ChatGPT and Codex, and Codex deep links should open Codex.

Actual behavior

Only ChatGPT is available. Codex is inaccessible until the app is downgraded to an older build.

Additional context

This is reproducible after logging out and back in. The same account works with an older desktop-app build.
