 > [!NOTE]
-> This API has a [known issue](https://microsoftgraph.visualstudio.com/Known%20Issues/_workitems/edit/40947). When this API is called with the `$expand=members` query parameter, the response returns a maximum of **25 member items**, even if a larger `$top` value is specified. This behavior differs from the expected behavior where the `$top` parameter controls the maximum number of items returned. As a result, applications that rely on `$expand=members` might not retrieve the full list of members in a single request.
