I’ve got response from the related Team.
We did introduce a change to the way the VSTS Content Pack queries the REST APIs to prevent it from throttling VSTS on our largest accounts. If the data refresh is timing out on the content pack the primary alternative is using the Analytics OData endpoint. The preview for OData is currently closed but because the customer is blocked from using the Content Pack we will make an exception.
To start using the 3 new Widgets and OData the customer will need to install the Analytics Extension on the account - https://marketplace.visualstudio.com/items?itemName=ms.vss-analytics.
Examples of how to use the Power BI extension (VSTS.Feed) can be found here: https://www.visualstudio.com/en-us/docs/report/powerbi/data-connector-functions
A general overview of the OData endpoint can be found here: https://www.visualstudio.com/en-us/docs/report/analytics/overview-analytics-service
A more detailed overview of the aggregations we support can be found here: https://www.visualstudio.com/en-us/docs/report/analytics/aggregated-data-analytics.
We are working on some experiences which will improve the out of the box functionality with our OData endpoint and Power BI which is currently planned for early next year. We do not have any plans to update the Content Pack at this time.
Best Regards,
