I have two tenants, A and B, and B tenant has guest users from A tenant. They use Power BI Service, everything works apart from:
everywhere with the input field where you put users name, such as adding users to a workspace, or when adding permissions to an app, the name/account suggestions don't come up, which means no users can be added. Even copy and pasting the UPN doesnt work, it's like the guest account is not reading the AAD of the tenant. With "home" account in this tenant, everything works - if i start typing a user name, suggestions come up. But doing the same with the guest account in this tenant, it's like the guest account doesnt have access to AAD.
This is the same problem, without solution https://community.fabric.microsoft.com/t5/Issues/Adding-Users-to-a-Workspace-does-not-work/idi-p/2477951
Any advice will be much appreciated
Users with their type set to "Guest" cannot enumerate users in the tenant. If you change their type to "Member", they should be able to then.
Note this is a separate thing from invited/local accounts. Invited users just get the "Guest" type by default. But it can be changed.
