The email you provided is not supported

I finally found a solution on YouTube after a very long period of irritation. Let me share it with you too. It works for all.
Here it is: How To EASILY Fix "The Email You Provided is Not Supported" in Chat GPT /OpenAI - YouTube

This is the issue I was having too.

OPenAI apparently is using a filter in their test designed by a highschool kid–channeling their inner bill gates? Also, the “your email is not supported” is the title of the web page that they use for the successful account creation page. So, yes, some failures (and all successful attempts) will cause those words to show up.

They don’t seem very good at this website thing.
