Filled map issue with counties in Connecticut

[npnigro]

Some of the polygons for Connecticut counties stopped working recently. All other counties in the U.S. work with this visual. If I add in the Lat/Long, then the map changes and gets a little better, but is still wrong. This is an issue with the Azure map visual and the native fill map visual. See image below without Lat/Long:

Hi @npnigro 

What should a Filled map look like under normal circumstances?

The entire state should be filled in.

I've noticed the same issue with Connecticut. My maps used to fill in the entire state and new issues with individual counties are resulting in bare and overlapping regions (resulting in darker patches), as shown in Figure 1. I've tried to find a workaround and not yet found anything that works.

The issue of overlapping and missing shapes appears to be with four counties:

• Fairfield County, CT - Shape appears to generally wrong and particularly missing a chunk from the ESE, resulting in a gap to the east between it and New Haven County, CT
• Hartford County, CT - Shape is equivalent to Tolland County, CT
• New Haven County, CT - Shape appears to be generally wrong and particularly missing a chunk from the WNW, resulting in a gap to the west between it and Fairfield County, CT
• Tolland County, CT - Shape is equivalent to Hartford County, CT

As a more general issue, all of the county shapes for Connecticut appear to be wrong, which can be seen by comparing the Power BI county map (see Figure 2) with a set of ground truth shapes (Figure 3), found through a search of the CT state website [CT Vicinity County Polygon | CT Vicinity County Polygon | CT DEEP GIS Open Data Website (arcgis.com)].

P.S. Here's what the continguous US currently looks like in Power BI with all counties filled in. It's a fairly small blemish when looking at the entire country, but becomes pretty unmistakeable in analyses that focus in on the northern east coast.

Any updates on whether a solution is in the works for this issue?

I have the same issue with my Power BI - Filled Map

@v-yetao1-msftany plan to investigate this issue, seems like we are encountering a particular mistake in the filled map for Connecticut.
