Updated to Current Brach 2309. Tried to upgrade CMG from classic and it failed. We deleted the original CMG from console and Azure. Cloud Service, WebApp and ClientApp creates with no issue. When attempting to create CMG, after clicking sign-in the console crashes. On the SMSAdminUI,log we get a Failed to get permissions for sign in user with status code BadRequest. Attempt to do via PowerShell and it fails with Failed to get permissions for sign in user with status code BadRequest. User account signing is Azure Owner/Contributor and Global Admin via PIM.
