I can no longer access the GPT-4 model on a specific user

Dear Forum mermbers.

I am currently using a paid account with multiple sub-accounts. Until recently, I had access to GPT-4. However, I have noticed that one of my accounts no longer has access to GPT-4, while my other accounts still maintain this access.

I’m wondering if anyone has encountered a similar issue or knows why this may be happening. I would greatly appreciate any assistance or insights you can provide.

Thank you in advance for your help!

Best regards,
