What issue are you seeing?

After updating the macOS desktop app to version 26.707.31428 (“Powered by Codex & OWL”), installed plugins appear normally and can be attached to prompts, but their callable tools are unavailable in every new conversation.

Plugins continue to work in ChatGPT Web with the same account.

What steps can reproduce the bug?

1. Open ChatGPT/Codex Desktop on macOS.
2. Confirm that Gmail and Computer Use are installed.
3. Start a new conversation.
4. Explicitly attach Gmail.
5. Enter: Show the subjects of my three newest emails.
6. The app responds: I can’t access Gmail data in this session because the Gmail connector tools aren’t available. Please reconnect Gmail, then ask again.
7. Attaching Computer Use similarly does not expose any callable Computer Use tools.

What is the expected behavior?

_No response_
