Bug: Incorrect sorting in "Recents" view / Missing recent chats and maybe broken search index

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

ChatGPT 26.980.... codex-cli 0.149.0

What subscription do you have?

Pro

What platform is your computer?

Darwin 25.6.0 arm64 arm

What issue are you seeing?

It's happening at the desktop chatgpt app and in the browser version.

Since today, the "Recent conversations" (Recents) view is no longer displaying current data. The sorting behavior appears to be corrupted, leading to the following issues:

IChats that are approximately 1-2 years old are suddenly appearing at the very top of the Recents list.

Missing Chats: At least one chat that was actively edited yesterday is completely missing from the Recents view where it should be at the top.

eventual Broken Search Index: The missing chat cannot be found using the search function, suggesting a potential search index corruption or an issue with the local database/cache syncing. hard to tell as I cannot see the recent list correctly plus not finding a specific new issue in the search index. Chat could be deleted forever or just not indexed plus not in recent chat list.

What steps can reproduce the bug?

1. Open the ChatGPT app / or browser chatgpt.com and login.

2. Check 'recents' on the left sidebar. (very old ones there, new ones not)

3. Attempt to find a conversation that was edited yesterday via the search bar. (I've searched for 2-3, and at least one is not to be found.

(it seems that chatgpt app and browser version do not share every conversation, probably the local ones are not visible in the web browser which I could understand. But the missing chat is nowhere findable, and the recents list is everywhere wrong.)

What is the expected behavior?

• recents show the most recent chat lsit.
• content of a recent (or all) chats is findable using the search function
  • e.g. I search for 'ManifestNodes' which was more than once mentioned in the chat to be found, doesn't return the corret one, neither web nor app.

Additional information

I'm using ChatGPT and Codex somtimes same time in various environments:

• VSCode Codex extension
• ChatGPT app locally
• ChatGPT web browser version
  I use all of them in chat & work mode and sometimes switch modes of a chat itself.

The report names no repository files, tests, or entry points; first determine whether Recents and search are implemented in this repository or belong to external ChatGPT services. Reproduce the missing and incorrectly sorted conversations across the app and browser, then identify a verifiable fix covering recent ordering and search visibility.
