Checking the data source connections and refresh schedules for the affected dashboards This step directly addresses the potential issue by ensuring that the dashboards are properly connected to the data sources and that the refresh schedules are correctly configured. Option A is incorrect because rebuilding dashboards is time-consuming and may not address the underlying issue with data refresh. Option C is incorrect as transitioning back to an on-premises server is a drastic step that doesn't directly solve the issue with data updates. Option D is incorrect because limiting user access does not address the issue of data not updating in the dashboards.
