Hello, I am replicating the demo for Lakehouse monitoring found here: https://notebooks.databricks.com/demos/lakehouse-monitoring/index.html

For some reason, my dashboards show empty, i.e., they say 'no data' - like nothing fits the criteria from the underlying sql queries. I tried separately on wine dataset as well (by adding the artificial timestamp column) and the same thing happens. 

Can someone help me understand why? Usually I can query the data with sql and I had no problems couple of months back - did something change in the meantime or should I check with my system admin?
