I am using the custom Power KPI visualisation for reporting on several KPIs
in the designer i have the visualisations working, a green tick for good and a red x for bad
when i deploy the report to the on premise report server, the tick and cross visualisation doesn't appear
In my test, the custom visual Power KPI displays well on PBI Report Server. I used IE 11 to log on Web Portal. In your scenario, please refresh the web page or change to a different browser for a test.
