Ask HN: Anyone accepted into OpenAI "Codex for open source"?

Anyone been successfully accepted into Codex for Open Source? (https://openai.com/form/codex-for-oss/)

I was accepted on Aug. 10th with an Email "You can just build things, enjoy 6 months on us", but couldn't redeem my code because I had an existing paid subscription. I was told to let the subscription expire, which I did. A month later I tried to redeem the code, but it's saying my promo is invalid. I reached out to OpenAI support and they said they can't regenerate the code and that I'm no longer eligible.

Anyone else had this issue, or was it a smooth acceptance process for you?
