Confirming there is a problem with at least Enterprise users.
Hi John, Lerg,
John, can you please try it again? There may have been a minor issue with your Enterprise license, but it should be fixed now.
Lerg, your issue should also be fixed. Can you confirm so?
Thanks,
Brent
Brent, yes, everything is fine now, thank for a fast fix!
It totally works again!

We are investigating.

Can you all try again? Engineering is in the process of putting in a fix. After you log in you may have to quit the simulator and restart to have it remove the Starter label.
