What issue are you seeing?

In the past few days orchestration of tasks via the codex desktop app is no longer working.

Up until last week, I could leave the desktop app open on Mac and connect via Windows via the app. Through Windows then, I could send messages via my main "orchestrator" task which would then prompt other "sub" tasks.

This is now no longer working. Codex says:

I prepared the bounded prompts, but they were not delivered: the Codex task-coordination service became unavailable after the remote reconnect. Desktop control is also prohibited from operating the Codex app, so I cannot safely bypass it.

Again, I'd like to highlight the fact that this was working just fine for the past few months up until last week more or less.

Now instead, I can't keep the Mac app open because when I try to access the same task via Windows, Codex will complain with something along the lines of "this conversation is open in another app..." and doesn't allow me to send prompts anymore.

Codex will sometimes try to use the CLI instead which obviously breaks the whole workflow.

What steps can reproduce the bug?

1. Start an orchestration task on Mac
2. Close the Mac app
3. Use the desktop app via Windows remotely connected to the Mac
4. Ask the orchestration task to prompt the "sub" tasks
5. Observe the issue

What is the expected behavior?
