Developer Tools not available on Tools Menu

The Developer Tools are not available on Tools Menu for my site. Could you please assist?

Are you menber of beta program?

Yes I am. I received the approval email on Aug 6.
I have 2 existing sites for which the “Developer Tools” options does not appear.
I created a new site and the “Developers Tools” option appeared.

Q: Is it possible to migrate or upgrade the site to support the “Developer Tools”?

Hi James,
we have fixed an issues with our user approval system.

did the issue resolve itself?

I also have trouble with this
