What issue are you seeing?
After today's Codex App update, my project chat history disappeared from the sidebar/project list.
I did not delete or archive these chats manually. The projects themselves are still visible, but several repositories/projects now show “No chats”, even though they had existing conversations before the update.
This affects multiple projects/repositories, not just one. Some recent chats are still visible in other projects, but many previous chats inside projects disappeared from the UI.
I logged out and logged back in, but the chats still do not appear.
This is a serious issue because these chats contain important project history, repository context, previous debugging work, and implementation decisions.
What steps can reproduce the bug?
Feedback ID: no-active-thread-019eb0b1-2a37-73d3-900c-1433a566cc19
Steps to reproduce:
- Open Codex App after the latest update.
- Check the sidebar/project list.
- Open projects/repositories that previously had existing chats.
- Notice that some projects now show “No chats”.
- Log out of the Codex App.
- Log back in with the same account.
- Check the same projects again.
Actual result:
Previous project chats are still missing from the UI. Several projects show “No chats”, even though they had existing conversations before the update.
Expected result:
All existing project chats should remain visible after the update and after logging back in. The update should not hide, remove, or desync project chat history.
What is the expected behavior?

Ditto here. I can find the chats if I switch the view to chronological but I can't view them by project.

After updating to the latest version of Codex today, my Windows 11 laptop started freezing when I type longer messages in Codex.
The first time it happened, I had been using Codex for about 30 minutes. The laptop suddenly froze and restarted by itself. After restarting, Codex appeared to reset all settings to default, including my previously created project chats.
Now the problem happens consistently whenever I type a longer message in Codex, making the whole laptop unresponsive. I cannot continue using Codex safely until this is fixed.

The same here. I can only see chat threads "3d" old (before the weekend) - all other older disappeared from Codex App UI.
Note that this is only UI "feature". Chat threads are still sitting on your disks. And you can ask Codex to locate them and it will return ID which you can reopen using Codex CLI and resume call. Though resume will not make them visible in UI - it will just reopen them in command line. The only workaround Ive found is: fork resumed thread. It will then become visible in UI as new thread.
Ive had a chat thread with heartbeat automation which has been working for weeks. But after last Codex upgrade this got broken. Even though the chat thread is actively and daily used, Codex decided to classify it as old and removed it from UI which broken the automation - automation execution says it cannot be started because the chat thread does not exist anymore.
This is very inconvenient. Why cant Codex UI show all old chat threads?? Whats so bad on that that Codex has to be removing them? Hiding older ones (as UI convenience) I could understand. But removing them breaks not only automation but also user's mental picture which often relies on older references.
The workaround: as I said above, fork removed chat threads from Codex CLI.

I think ⬆️ did it for me. I updated this morning and I see my old project chats now! Thanks.

FYI: I dont think above fork based workaround is reliable. It worked earlier but now my automation and threads I pinned (to preserve them) are broken again. Codex app got updated at least 4x in past two days and it is getting worse. I filed Codex generated deep evaluation on broken pinned and forked threads as #28607

OMG! I just experienced the same thing again. All my project chats are gone, there isn't a trace whatsoever, completely gone like I just opened a new account. I actually thought someone was trying to steal my projects because something similar happened on GPT before I moved to codex, the main database history, core conversations and frameworks in between were erased, I was left with the non important things at the beginning and the end, I only noticed when I wanted to make reference to one of the conversations and also download as pdf, it was so annoying. I really hope it's not the case of ideas theft.

Still occurring

I can reproduce this consistently on Windows.
The issue seems to affect Codex tasks inside Projects specifically.
Steps to reproduce:
Result:
Important detail:
At the same time, a normal Codex chat outside of Project tasks survives the app restart correctly. So this appears to be specific to Project task history persistence/rendering, not a general chat-history issue.
I reproduced this again today on a fresh task, so for me this is currently blocking normal work in Projects because every app restart can make the latest task history disappear from the UI.
