Chatgpt pro plan is not working

My ChatGPT Pro subscription appears to have lost its entitlement. The issue first appeared in the Codex app with the error:

The 'gpt-5.6-sol' model is not supported when using Codex with a ChatGPT account.

Shortly afterward, my ChatGPT account started showing “ChatGPT Free” even though my billing page shows my Pro subscription as Paid. My account email and billing email are the same.

Yes, I have a similar issue in ChatGPT Business, with the Pro option now being gone, even though I have sufficient tokens; and that is the same for gpt 5.6 and 5.5.

I am having the same issue, how did it resolve for you guys? How long it took? I am struggling with a tight deadline and I am sweating and suffering hard mode.

It is not resolved yet, i haven’t heard back from them, not even a bot replied.

Thank you for bringing this to our attention.

If you've already reached out to Support, could you please share your support ticket or case number here? I'll be happy to take a look on my end and see if there's any update or anything further I can investigate.
