Purview Data Quality Dashboard/ Report - Refresh

Hi All,

Currently I am getting all blank in Purview Data quality dashboard, before two months dashboard shows all values across each data quality dimensions and showed graph for each quadrant in a dashboard. After two months when checked the dashboard everything is blank nothing is shown in the report. (Note : I have created two governance domain and each domain has five data products assigned with data assets, implemented data quality rules on top of each data assets that time scores were reflected in the Purview data quality dashboard), but suddenly now it all went blank scores showing as 'blank'

Note : None of the data quality assessment were not deleted during that two months, data quality rules are still active and its still showing scores at data asset level. But its not showing in the dashboard currently.

Can you please help me to sort out, is there any refresh policy associated for Purview Data quality dashboard.
