When I expand a group into details, is it supposed to rerun the entire data request to the datasource? Also it takes an extremely long time when expanding sections.

Hello Donald,

The described behavior is expected and the data from the data source is retrieved every time an Action has been executed.
The loading time when expanding/collapsing sections depends on a lot of different factors such as the amount of data retrieved from the data source, the available system resources, etc.
For more information on how to optimize your report, please follow the Performance Considerations help article.
