Hi again,
The answer Kushgara provided above was about “creating Search Index”. And from the details you have provided, I deduce other units also use Atlas CLI in the labs.
I have, moments ago, tried the lab in the unit I mentioned and it has passed the first check with “1 project in the selected organization” and passed the second check after I moved a few other projects into that organization.
So it is safe to assume this “create new account” problem is solved. However, be aware of possible clashes of projects (as stated in the linked answer) if you do not use Atlas CLI properly in the future with multiple organizations/projects/clusters.
