Dynamic hierarchy using fields parameter works on desktop but not on cloud service

Hi Dominoes2 ,

To find your current Power BI Service version, open Power BI in your browser, click the question mark icon at the top right, and choose About Power BI  from the dropdown. A pop up will show information like the Service version, Client version, data location, and last update time.

This feature gives you the latest build details, but Microsoft does not provide a complete public version history. Detailed version logs with release dates are usually from internal dashboards, which are not available to the public.

If you want to make it even more polished for a community post or documentation, you could add a quick note about alternative resources like:

Previous monthly updates to Power BI Desktop and the Power BI service - Power BI | Microsoft Learn
Use semantic model version history (preview) - Power BI | Microsoft Learn

Hope this helps...

That page is a SharePoint list we maintain internally with Power Automate to keep track, precisely because Microsoft are very secretive about service version changes.
