I’m in the AWS sandbox, I can’t create organizations…this by design? Or, more to the point, why is the account locked down to not allow organization access.
As to why: Cloud Guru probably uses an Organization to provision/manage the sandbox accounts. But that’s just a guess.
AWS Organizations is not available in the sandbox: https://help.acloud.guru/hc/en-us/articles/360001389256-AWS-Cloud-Sandbox
