Files instantly expiring upon upload

I’m trying to do an excel project and I tried to upload the file but no matter what I do, it immediatly says it cant access the files because and I quote: It looks like the file you uploaded earlier isn’t available anymore — it expired from the system.

Anyone else getting this issue (I’m in US. I know EU has something similar)

UPDATE: apparently the team has identified the issue and working to fix it

I’m from the EU and it still doesn’t work to this day. I pay monthly and unfortunately it doesn’t work.

Today’s AI: the files you uploaded (sender.h etc.) are now reporting them as expired, so I can’t make an exact patch for your specific code

It’s just impossible to work with.

This has been happening to me on every upload, at least for .cpp and .h files, for well over a week. It feels a bit like I’m being forced to use Codex or Agent mode.
I do wonder if it is related to uploading files having the same name as previously uploaded files. I tried appending 01, 02, 03, for example, as a type of version control, and it seemed to work. But I’d rather not have to do that.

Was this resolved for you? Since December I’ve been facing this kind of problem with .cpp/.h files, and using Xcode seems to solve it, but for brainstorming it’s terrible.

It has remained an issue, but I’ve since switched much of the coding to Codex CLI. So I should say that I have not given it an opportunity to fail in this way in the last week, so I don’t know if the issue has been addressed by OpenAI.

I even wonder if this has been a deliberate ‘bug’ to motivate users to use codex. Having the codex agent have instant access to all project files and have it be aware of its current state has been a tremendous improvement. I no longer need to keep uploading files to ensure that the agent is awate of the current state.

Even if the issue were fixed it probably would not solve the problem of the agent referencing older code, since there ends up being so much for it to keep track of.

So my suggestion, if possible is to use the CLI agent. I know this isn’t possible for everyone, and the issue should be addressed…not everyone wants to create a codex project everytime they want assistance with code.
