My suggestion is to use mapshaper.org and use the "Simplify" feature.  You will find that by reducing the complexity of your shapes up to as much as 50-60% you can visually get about the same map.  For example, I have a map of all the counties in the U.S. which is approximately 3000 shapes.  The total file size is 1.25 MB.    It's not as much a Power BI problem but a PC/device issue trying to render lots of detailed Polygons.  Use mapshaper to reduce the detail of your shapes and it should render faster.

Thanks for the suggestion. I will give it a try. Hopefully, it won't have the similar behavious as the Esri Map into which I published the same data and used in other GIS applications without problem. It was simplied on the fly when it loaded into the Power BI.
