macOS: final task answer missing after ending voice during Thinking, despite completion notification

Environment

Checked on September 12, 2026:

• Desktop app version 26.908.40834, build 8881, installed as ChatGPT.app and running a Codex task.
• macOS 26.6.2, Apple Silicon (arm64).
• Subscription: ChatGPT Pro.

Observed steps

1. During a voice conversation, ask the assistant to perform a task. The assistant acknowledges the request and the task enters Thinking.
2. End the voice session while the task is still in Thinking.
3. Later, receive a notification stating that the work is complete or the findings are ready. The notification includes [COMPLETE] followed by report text.
4. Check the task's conversation. The task's final answer is not displayed.

Observed behavior

In my environment, this happens every time I follow the steps above. The completion notification arrives, but the corresponding task answer is absent from the conversation.

In one inspected occurrence, the local session record contained the full final answer even though it was not visible in the conversation.

Reference

Voice exit leaves hidden overlay owning the thread; primary UI remains thinking describes a similar symptom after ending voice. Whether the issues are related is not yet known.

Start by reproducing the voice-ending flow on the macOS desktop app: begin a Codex task, end voice during Thinking, and inspect the completion notification and conversation. Compare the conversation with the local session record, which contained the full answer in one occurrence. Done means the completed task answer is visible in the conversation after the notification arrives.
