GPT-4 API access granted but 404 error

I have a similar problem - I received an email 3 days ago saying I have GPT-4 API access, but I can’t access it. The model doesn’t show up in the playground and the API errors with “InvalidRequestError: The model: gpt-4 does not exist”.

I’ve doubled checked and the receiving email address matches my account email. Anyone else have this problem?
