Codex Desktop 26.527: `Copy as Markdown` disappeared from the Copy menu

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

Codex Desktop Version 26.527.31326 (3390).

What subscription do you have?

ChatGPT Pro.

What platform is your computer?

macOS, using the Codex Desktop app.

What issue are you seeing?

After updating to Codex Desktop 26.527, the previous Copy as Markdown option appears to have disappeared from the Copy menu.

In the top-left chat/menu Copy submenu, I now only see:

Copy working directory
Copy session ID
Copy deeplink

None of these options replaces the old Copy as Markdown behavior. They only copy metadata or a link, not the actual Codex session / chat content in Markdown format.

This is a significant workflow regression. Copy as Markdown was important for:

• transferring Codex session output into GitHub issues;
• preparing support reports / bug reports;
• saving session notes into external docs;
• preserving code blocks, Markdown formatting, and assistant responses without manually selecting the UI text.

I do not see an obvious changelog note or migration path explaining where this functionality moved. If this was intentionally removed, please consider restoring it or replacing it with an equivalent export/copy action. If it was only moved elsewhere, the UI currently makes it hard to discover.

What steps can reproduce the bug?

1. Update/open Codex Desktop 26.527.31326 (3390) on macOS.
2. Open an existing or new Codex session.
3. Open the top-left chat/menu area and expand the Copy submenu.
4. Observe that Copy as Markdown is no longer available.

What is the expected behavior?

The app should still provide a clear way to copy/export the current Codex session or chat content as Markdown, preferably in the same Copy submenu or another clearly discoverable location.

What is the actual behavior?

The Copy submenu only shows metadata/deeplink options and no longer provides a Markdown copy/export action.

Additional information

This is separate from earlier problems with Copy as Markdown embedding screenshots as huge inline base64 data URIs. The problem here is that the Copy as Markdown entry itself appears to be missing entirely after the update.
