Hi,
Logan is super busy keeping lots of projects on the go at any one time. If you do get a reply, it may take some time.
In the mean time can you check a few things for me, do you have more than one account or organisation with OpenAI? If you have more than one, can you check that the organisation that has the > 1$ GPT API bill is the same as the one you expect to get GPT-4 access with, as this can be a source of confusion, also make sure you are logged in to the correct account.
When you are logged in, can you check on the playground by ensuring you are in Chat mode

and, finally can you try generating a new API key and checking after doing that.
Thanks for your time, I know it’s frustrating when things don’t work as smoothly as they should, know that you will get access by the end of the month regardless.
