Signals Notebook: My account is blocked, I got an AADSTS50105 error

The error message is related to SSO system configuration, Azure/Entra. The configuration is being performed by client and Revvity does not have access to it. If you have got the AADSTS50105 error, you will need to follow with  your company internal IT team to verify that the Entra application is properly configured to integrate with Signals Notebook.
 
There is an article from Microsoft that explains the problem: https://learn.microsoft.com/en-us/troubleshoot/entra/entra-id/app-integration/error-code-aadsts50105-user-not-assigned-role
 

The user hasn't been granted access to the application in Microsoft Entra ID. The user must belong to a group that is assigned to the application, or be assigned directly.
