According to this doc: https://docs.microsoft.com/en-us/dynamics365/common-scheduler/developer/extensibility-release-notes#december-2017, when changing the dates on the Schedule Board, the Resource Query is not automatically executed again. Rather, you must click the search button to re-execute the search using the new Schedule Board visible dates.

However, in the new Schedule Board, there is no Search button. We have to click Search Resources box and click Enter as workaround. It would be great if we can bring the Search button back.
