I have also been stuck on the waitlist. Reached out to support last night and after the agent did some digging they said it sounded like an issue with the sheer volume of requests that have come in for Early Access. He said it created "a recoverable problem with the server", basically it sounded like either a back up or a crash or some kind. He had said to reach out again today if it wasn't resolved by mid-day, and I'm currently on the phone with Developer support. I'll share what I find out here.
