Discovery of external dataset does not work anymore

[arthur89]

Hello,

Our guest B2B users can no longer discover our shared power BI dataset in their power BI service.

The dataset is hosted on a power BI premium capacity

We checked every step of the documentation (all settings OK, access and free license granted) Distribute content to external guest users with Azure AD B2B - Power BI | Microsoft Learn

Note that the dataset is still accessible for them with the XMLA endpoint on power BI desktop.

It used to work a few weeks ago so we wonder if there has been some kind of regression on this feature

Thanks for your help
