When you create a security group in Azure AD that has external B2B users in it, and then grant this security group access to your Power BI App, the B2B users still can't access the App. If you grant...
1. Yes, the external user gets the email.
2. Data source is sample data I created in Power BI Desktop by clicking "enter data".
3. The user is denied access when clicking the link.
4. The error message says can't find this app.
