codex - 💡(How to fix) Fix Mobile Remote briefly shows a local project/thread, then removes both after sync

What version of the Codex App are you using (From “About Codex” dialog)?

What platform is your computer?

Darwin 25.4.0 arm64 arm

What issue are you seeing?

When using Codex Mobile Remote with Codex Desktop on macOS, one local git workspace is not persistently visible on mobile.

A newly created thread in that workspace appears on mobile together with the project for approximately 10-15 seconds, then both the project and the thread disappear. Other projects on the same Desktop Remote connection remain visible.

The thread remains available locally in Codex Desktop after it disappears from mobile.

What steps can reproduce the bug?

1. Connect Codex Mobile Remote to Codex Desktop on macOS.
2. Open a local git workspace in Codex Desktop.
3. Create a new thread in that workspace, for example with prompt: Remote environment visibility test 3.
4. Observe the mobile Remote project/thread list immediately after thread creation.
5. The project and the new thread appear briefly.
6. Wait approximately 10-15 seconds.
7. The project and thread disappear from mobile, while the thread remains present locally in Codex Desktop.

Additional observations:

• Other local projects on the same Mac and Remote connection remain visible on mobile.
• The affected workspace has multiple existing local threads, none persistently visible on mobile.
• A newly created thread consistently reproduces brief visibility followed by disappearance.
• I initially encountered a local worktree environment setup failure, corrected it, and confirmed that new thread creation succeeds. The mobile disappearance still reproduces after thread creation succeeds.

What is the expected behavior?

Once a local project and its newly created thread are visible through Mobile Remote, they should remain listed and accessible while they still exist in Codex Desktop.

Additional information

This looks like live thread/project events are delivered successfully, followed by a persistent project/thread synchronization or filtering pass that removes the affected workspace from the mobile view.
